Technical FAQs

Adding viewing and document conversion capabilities to an application can be a daunting task, especially when a development team is facing resource constraints and a tight schedule. That’s why many developers turn to API-based viewing integrations like Accusoft PrizmDoc Viewer instead of building those features from the ground up. By leveraging the versatile power of HTML5 viewing, they can quickly expand software capabilities without having to rethink the basic framework of their products.

What’s Under the Hood of PrizmDoc Viewer?

To understand how PrizmDoc Viewer goes about rendering documents in a web application, it’s helpful to take a closer look at its underlying architecture. There are two primary components that work in concert with the application’s web server: the HTML5 viewer and the backend.

The HTML5 viewer is integrated to run in the browser, typically via a web page or portal that serves as the front-facing aspect of the application. This is where document content is rendered as SVG elements. Since the viewer uses HTML5 to display content, it isn’t dependent upon any specific word processing software or imaging program.

Most of the heavy lifting is handled by the PrizmDoc Viewer backend, which consists of the PrizmDoc Server and PrizmDoc Application Services (PAS). PrizmDoc Server is the core computing component. It performs the actual conversion process to convert document pages to SVG, but it doesn’t have any permanent storage. Converted content and annotation markups are instead stored in PAS. The PAS component primarily handles long-term storage and hands files off to the server for conversion or processing. 

Critically, PAS also has privileged access to other storage locations used by the application, such as file systems or databases. This allows it to easily retrieve source documents and hand off tasks to the server.

The Role of the Web Application

The web application server sits between the HTML5 viewer component and the backend component. It functions as a reverse proxy that relays requests between the two, passing content requests from the viewer to the backend and then delivering converted SVG content from the backend to the viewer.

PrizmDoc Viewer doesn’t actually work with the source documents in the application’s storage. They remain safely unaltered while the backend generates a converted version for viewing and annotation. The web application typically only makes REST API calls to PAS. Background conversion that doesn’t involve the viewer, however, can be performed by making a direct call to PrizmDoc Server.

Making the HTML5 Magic Happen: Viewing a Document

When the web application has to open a stored document for viewing, each component of PrizmDoc Viewer plays a special role in the process. Everything begins with the web application sending a request to PAS to create a new viewing session. How this session is created depends upon how the backend is deployed. In most cases, it will be self-hosted as part of an on-premises deployment or through PrizmDoc Cloud services.

Once that session is created, PAS generates a new viewing session ID and passes it back to the application. All of this happens before any conversion or viewing begins, but the application can begin rendering to the HTML5 viewer by configuring it to use the viewing session ID. This brings up the viewing UI immediately, which will ultimately save time as the document is prepared.

The web application then uploads a copy of the source document to PAS, which can be in any number of formats supported by PrizmDoc Viewer. As soon as PAS receives the document, it begins handing off pages to PrizmDoc Server for conversion to SVG. Since pages are converted one at a time, PrizmDoc Viewer is able to open and view documents in the browser before the entire file is converted. That means less time is spent waiting around for large documents to be prepared for viewing.

As soon as the HTML5 viewer loads in the browser, it begins proxying requests to PAS through the web application for the first pages of content. Once the converted SVG content is available, PAS hands it back to the web application, which then passes it along to the HTML5 viewer, which displays that content in the browser. Additional pages are delivered as they’re ready, and the viewer may make subsequent requests as the user continues to interact with the document.

While the viewing process involves several steps, it is typically performed so quickly that the end user doesn’t experience any significant delays. Larger documents may take more time to render as SVG content, but even in these cases, PrizmDoc Server’s ability to render and deliver each page to the HTML5 viewer as it becomes available allows users to begin viewing documents within their browser right away.

Enhance Application Viewing Performance with PrizmDoc Viewer

As an API-based HTML5 viewing solution, PrizmDoc Viewer can be integrated into most web-based applications to support a broad range of file formats. Developers can use its annotation, redaction, document comparison, and conversion capabilities to deliver a full range of document management tools within their software platforms rather than having to build them from scratch.

The ability to view PDF files has become an essential feature for web-based applications. While dedicated desktop readers are still common, the average user justifiably expects to be able to view documents without switching between applications. Thanks to browser-based PDF libraries like PDF.js, developers can both integrate the viewing features they need and build the next generation of PDF viewing integrations.

What Is PDF.js?

An open-source JavaScript PDF library, PDF.js was originally developed by the Mozilla Foundation in 2011 to serve as the built-in PDF viewer for the Firefox web browser. At the time, web browsers depended upon separate reader applications or browser plug-ins to view PDFs.

Unfortunately, this created several security risks. External plug-ins can contain malicious code or gather data that could endanger privacy. Downloading PDFs for local viewing is also potentially hazardous because it means the file must be removed from a secure application environment.

PDF.js uses Asynchronous JavaScript and XML (Ajax) to render PDFs as an HTML5 <canvas> element directly within a web application. Since it uses JavaScript for rendering, PDF.js is compatible with all modern browsers and doesn’t require any additional plug-ins.

In addition to being integrated into Firefox, the software was also made available as open-source code. This made it possible for independent developers to expand upon the core capabilities of PDF.js in the years since its release.

Should You Build or Buy a PDF.js Viewer?

The open-source availability of the PDF.js library makes it an attractive solution for software teams looking to add native viewing functionality to their applications. As with many open-source frameworks, however, developers may quickly run up against a few complications when building out a viewing solution from scratch.

Out-of-the-box, PDF.js consists of three basic layers:

• Core Layer: The heart of the JavaScript PDF library, this layer parses and interprets binary instructions from the file itself.
• Display Layer: This interface handles the actual rendering of the PDF into a <canvas> element.
• Viewer Layer: The primary viewing interface that allows users to view and interact with the document.
  

While the core and display layers can handle most documents, PDF.js doesn’t support the full PDF specification and sometimes struggles with rendering lengthy, complex, or image-heavy files. Overall performance is often on the slow side, and the way text is rendered makes text search somewhat unreliable.

More importantly, PDF.js lacks out-of-the-box mobile support. The included viewer doesn’t provide essential mobile UI features like pinch-to-zoom. It also doesn’t respond dynamically to mobile screens to ensure that menus and tools remain usable on all devices.

Any developer looking to add PDF viewing and editing capabilities to their web applications using PDF.js will need to solve these core issues. While features like responsive, mobile-friendly viewing may have been less important when PDF.js first released in 2011, they are considered essential by most users today. Unfortunately, building out these capabilities takes time and resources, which is something that few development teams have in abundance.

Integrating a ready-made viewer that combines the solid foundation of PDF.js with the innovative features users expect allows developers to quickly meet their project needs without pulling attention away from key aspects of their application.

The software development industry is changing more rapidly than ever before. With new technology hitting the market on a regular basis, software vendors need to become flexible enough to adapt to the top coding trends if they want to remain competitive.

After a tumultuous 2020, the industry has seen a number of key trends emerge in the first half of 2021. Here are some of the top coding trends worth watching in the second half of the year.

Top 5 Coding Trends of 2021 (So Far)

1. Open-Source Evolution

Developers have been turning to open-source solutions for some time now as a quick way to integrate new features into their applications. While there are a lot of great benefits to using open-source code, it’s not always the simple solution that it appears to be. Substantial work may need to be done to implement the specific features an application requires. More importantly, open-source solutions rarely offer much in the way of support or security updates, and there can also be complicated intellectual property issues to consider when incorporating open source code into a proprietary application.

That’s why many innovative developers are using stable open-source solutions as a foundation for creating more feature-rich software SDKs. For teams building new applications, it’s often much easier to implement one of these integrations because it will require far less configurations and additional coding to get up and running. They can also get the benefits of dedicated support and not have to worry about whether their new integration will create any legal issues down the road.

2. UX Design

With the proliferation of Software as a Service (SaaS) platforms and the widespread use of open source development resources, it’s becoming easier for organizations to find the applications that suit their business needs. What they can’t always find, however, is a solution that’s easy for their employees and customers to use. That’s why the quality of an application’s user experience (UX) is quickly becoming a key differentiator in the software market.

Rather than implementing UX features at a later stage of the coding process, developers need to consider how users will interact with their solution from the very beginning. Software needs to be intuitive and easy to implement out-of-the-box. This applies equally to end-user products and developer-focused SDK integrations. No one has time to struggle with software that’s difficult to use. If a solution proves too cumbersome and hard to implement, customers will likely turn to a competing product that offers a better user experience. The more time developers spend considering their software’s UX, the better they’ll be able to adapt it to customer needs in the future.

3. Responsive Mobile Support

For many years, there was a somewhat artificial distinction between mobile software development and desktop development. But in a world where half of all internet activity comes from mobile devices, no developer working on web-based applications can afford to consider their software “just” for desktops. Just as website designers have been building pages that respond dynamically to different screen sizes and control interfaces, developers must also account for the unique characteristics of mobile devices.

The unique characteristics of mobile screens present specific challenges regarding the application’s user interface (UI). Simply providing standard desktop controls is bound to result in a frustrating mobile experience. Mobile responsive applications can accommodate touch-specific controls (such as pinch-to-zoom) without compromising the desktop experience at the same time. Developers must think about what kinds of devices their software solutions will be used on if they’re to build features and tools that will truly benefit their customers.

4. API Integrations

Today’s developers no longer need to build every feature their application might require from scratch. Thanks to a new generation of web API technology, it’s easier than ever to find software integrations that can quickly and easily add vital features without having to dedicate weeks of development time to building them. Understanding which web application features can be incorporated via a REST API helps development teams to focus their limited resources and time on the truly unique features that will help set them apart from the competition.

Utilizing web API technologies can streamline sprints and shorten development time significantly. That’s because much of the “trial and error” work of building a new feature is eliminated. Rather than designing and testing new capabilities for months, developers can simply implement a tested and proven web API integration within a matter of days. That helps to keep budgets under control and development schedules on track to make targeted launch days.

5. Remote Work

When the COVID-19 pandemic struck the world in early 2020, many software developers transitioned to a remote workplace arrangement. As other industries begin to tentatively return to the office, tech workers seem to have become quite accustomed to working remotely. According to a late 2020 survey conducted by Indeed, nearly half of participants reported that they now have the option to work remotely on a permanent basis, with 95 percent of them planning to do so. Perhaps even more telling, however, was the finding that 60 percent of tech workers are willing to take a pay cut in order to keep working from home.

Software vendors will have to accommodate these expectations if they hope to remain competitive when it comes to finding and retaining talent. Project managers should not expect work patterns to go back to the way they were before the pandemic. They will be better served focusing on how to organize remote work efficiently and how to provide the resources developers need to be productive while working from home. Transitioning to a more remote workforce is also allowing organizations to tap into a much broader pool of talent, which will help to bring more diverse voices and experiences into the development process.

Document viewing capabilities are no longer a specialized feature that require dedicated applications. Thanks to powerful software integrations, developers can now build PDF viewing into their solutions to create a better user experience and streamline workflows. The growing popularity of mobile devices, however, has posed a few challenges to development teams accustomed to building an exclusively desktop experience, especially when it comes to JavaScript PDF viewers. That’s why one of Accusoft’s key development goals has focused on making a JS PDF viewer responsive to mobile screens.

The Increasingly Mobile Internet

Since 2017, mobile devices have accounted for about half of global internet traffic. This trend has been fuelled primarily by a combination of improved cellular network coverage and the ever-increasing processing capabilities of the average mobile device. It’s hardly a surprise, considering that the latest smartphones are often the most powerful computing device people own. Even for consumers who own desktop or laptops as well, mobile devices make it easy to access internet services on the go, allowing them to manage finances, collaborate on work tasks, or utilize eLearning resources (or watch cat videos).

Today’s customers expect organizations to provide applications that deliver a consistent experience across all devices, regardless of screen size. The era of designing software exclusively for desktop computers and treating mobile support as an afterthought is long gone. If an application’s mobile experience doesn’t at least match that of the competition, customers will quickly make a change.

Viewing Challenges on Mobile Devices

Mobile devices can present a few challenges for application developers, especially when it comes to viewing documents like PDFs. While there are many PDF reader apps available for mobile platforms, they typically require users to download a file to local storage or to a cloud service in order to open a document. In addition to being inconvenient, this often leads to some presentation problems because the reader may not render the PDF exactly as the creator intended, especially if it’s not linearized.

Developers could, of course, rely upon the mobile browser to display documents, but this also introduces problems. As with external reader apps, the browser viewer may not render the document as intended, which creates an uneven user experience across multiple platforms. More importantly, the browser’s interface may lack key controls that enhance the viewing experience on mobile devices, especially if the viewer is little more than a basic PDF.js library.

PDF.js and Mobile PDF Viewing

The open-source PDF.js library was originally designed for Mozilla’s Firefox browser, but it has become the basis for a broad range of PDF viewers due to its flexibility. That’s partly why the Accusoft PDF Viewer uses PDF.js as its foundation. However, one area where that versatility is sorely lacking is with regards to mobile support.

More specifically, PDF.js doesn’t supply a UI that is responsive for different screen types. It was designed to render PDFs to a conventional computer display and provides the expected tools needed to navigate a document using a keyboard and mouse interface. Even if developers were to incorporate the PDF.js library into their application, they would still need to build a new user interface for mobile devices. Otherwise, key mobile viewing features like touch scrolling and pinch to zoom would be handled not by the viewer, but by the device’s touchscreen interface. 

While this might sound like a small distinction, it can actually create serious problems when it comes to rendering the document at different zoom levels. Essential features like text search may also be rendered useless by the poor interface, and the lack of thumbnail previews could make navigating the document tedious.

Making a JS PDF Viewer Responsive

Today’s developers need viewing integrations that offer out-of-the-box mobile support to deliver a consistent viewing experience. That’s why we built upon the foundation of PDF.js to create a responsive viewer interface that instantly adapts to any screen size. Easily integrated into any web-based application, the Accusoft PDF Viewer immediately determines what type of device is being used when a document is opened. If it’s a mobile device, the viewer replaces the controls used for desktop viewing with dedicated mobile controls designed for a touchscreen. 

Key touch features like pinch-to-zoom allow users to interact with PDFs on mobile and tablet devices just as easily as they could with a mouse and computer screen. That usability is the key component of making a JS PDF viewer responsive. Mobile screens should never be treated like conventional screens. By integrating a mobile-ready viewer into their web application, developers can ensure viewing consistency across platforms while also allowing people to access documents where they want and when they want them.

Integrate Responsive PDF Viewing in a Snap

Building an application that includes a JS PDF viewer responsive to mobile screens is easier than ever thanks to Accusoft PDF Viewer. As a flexible JavaScript PDF library, it integrates quickly into any web-based application with just a few lines of code and no complicated server configurations.

Electronic spreadsheets have been a mainstay of business operations since their introduction four decades ago, but the way organizations use them has changed significantly during that time. Today, the financial industry needs FinTech accounting software that facilitates online spreadsheet collaboration without creating unnecessary risk or disrupting workflows. 

Spreadsheets in the Tax and Accounting Industry

Although many tax and accounting firms use dedicated software solutions to manage complex financial workflows, they still rely on conventional spreadsheets for a variety of tasks. In fact, a recent study by Deloitte found that 62% of companies are still relying heavily upon spreadsheets for business insights. The data used to inform risk analysis, growth projections, and financial modeling is often collected and sorted in individual spreadsheet files by individual employees. In many instances, that data will eventually be transferred into a more sophisticated accounting platform, either through manual entry or an API integration.

Spreadsheets also play a critical role when it comes to presenting complex financial data. Whether it’s for an internal presentation to key stakeholders within the organization or a customer-facing report designed to relay important information about their business, tax and accounting firms routinely need to create, edit, view, and share spreadsheets. 

Although Google Sheets has gained quite a bit of traction over the last few years, Microsoft Excel remains the preferred spreadsheet solution for most financial industry professionals. Practically every CRM and CMS platform allows users to easily export data into Excel’s XLSX file format for convenient viewing, making it the de facto standard for most companies. Online spreadsheet collaboration is also easier than ever before thanks to public cloud tools like Office 365.

5 Major Spreadsheet Collaboration Challenges

Unfortunately, all of that ubiquity and convenience comes with a few drawbacks. There are also some inherent shortcomings with Excel spreadsheets that pose significant challenges to tax and accounting firms in particular.

1. Version Control

One of the great benefits of spreadsheets is their ability to track data over time, with new information constantly being fed into the spreadsheet formula to generate different results. Unfortunately, that typically means that the document could potentially be outdated the moment it’s copied, shared, or downloaded because a more current version might exist elsewhere. While cloud-based software like Google Sheets or Office 365 theoretically ensure that everyone is viewing and referencing the same document, if there are too many people making changes, errors can easily escape notice and break entire spreadsheet formulas (or possibly corrupt the file). Even then, people may clone their own version to work on independently, which creates the same version control challenge posed by Excel-dependent files. 

2. Security

Familiarity has a way of breeding complacency. That’s certainly true when it comes to sharing XLSX files. People are accustomed to sending and receiving spreadsheets over email and other messaging platforms. What they may not realize, however, is that 38% of malicious email attachments disguise themselves as Microsoft Office file types. The last thing a tax or accounting firm wants is for an employee to accidentally infect their network with harmful malware by opening what they thought was a spreadsheet. At the same time, even conventional spreadsheet collaboration can pose a serious security risk. Excel files offer limited security controls, and downloaded or shared files could be easily hacked to compromise important financial data. With more people working remotely in response to the COVID-19 pandemic, FinTech accounting software needs to account for the common security risks posed by home offices while still meeting consumer demands for high-speed, low-friction digital solutions in 2020 and beyond.

3. Asset Protection

Spreadsheets often contain more than just important financial data. The spreadsheet formulas buried within the many rows and columns of cells may represent important intellectual property for a tax or accounting firm. Any time a company shares a spreadsheet, it runs the risk of those formulas being stolen and distributed. Even if these proprietary assets remain safely tucked away within the spreadsheet, there’s still the matter of anyone with a copy of the file being able to use it however they want, potentially cutting into the firm’s business.

4. Workflow Efficiency

Managing a large number of independent XLSX files can quickly become burdensome for any organization. Take, for example, a situation where a tax firm’s customers must download a spreadsheet to enter their tax information and then send that file back to the firm so the data can be entered into its FinTech accounting software. Not only does this create numerous opportunities for manual errors, but it also introduces several unnecessary (and potentially risky) steps into the process. What if a file is not attached to an email? Or if someone downloads the spreadsheet, but then misplaces it? How does the tax firm verify that the version sent back to them is the most up-to-date version? This approach to spreadsheet collaboration ends up wasting time and is highly prone to mistakes.

5. Software Dependencies

While Excel may be the most widely used spreadsheet software in the world, that doesn’t mean every organization has access to it. Smaller companies and startups are much more likely to rely upon cloud-based tools like Google Sheets due to their low cost and ease of online spreadsheet collaboration. Although Google’s Chrome browser offers extensions capable of reading, viewing, and editing XLSX files, the conversion process is often imperfect due to differences in feature sets. Transferring data back and forth between Excel and other spreadsheet programs can create formatting problems and potentially break internal formulas. 

The PrizmDoc Cells Solution

One of the best ways for FinTech accounting software developers to address these issues is to simply integrate spreadsheet viewing and editing functionality into their applications. PrizmDoc Cells is a web-based spreadsheet editor that natively supports XLSX files by storing them on a secure server and allowing users to interact with them online through an Excel-like interface. 

Secure Spreadsheet Functionality

PrizmDoc Cells provides essential spreadsheet features within a familiar UI. After opening an XLSX file, users can review and edit cell content within a secure web-based environment. Firms can also restrict features to protect spreadsheets from errors and unauthorized alterations. 

No Microsoft Dependencies

Deployed entirely within a Docker container, PrizmDoc Cells can import, view, edit, and export XLSX files entirely within a firm’s FinTech accounting software or web-based application. No one needs access to a copy of Microsoft Excel to access files.

Manage End-User Access

In addition to hosting their source files securely within a proprietary server or private cloud environment, organizations can control what end-users can access within the spreadsheet. Proprietary data and spreadsheet formulas can be safely hidden from view to protect valuable IP.

Maintain Version Control

As an entirely web-based viewer, PrizmDoc Cells eliminates the need to email, copy, or download spreadsheets, ensuring that the file being viewed is always the most up-to-date version. Editing access can also be adjusted to ensure that only authorized users are able to make changes.

White Label Customization

Developers can easily remove all branding to seamlessly integrate PrizmDoc Cells with their applications and FinTech accounting software.

Say Goodbye to the Old Way of Spreadsheet Collaboration

Today’s tax and accounting firms need to work more efficiently than ever before to keep up with the demands of their clients. They can’t afford to keep relying upon outdated approaches to spreadsheet collaboration. The pressure is on for FinTech developers to build applications capable of accommodating their security, workflow, and version control requirements when it comes to spreadsheets.

Managing and viewing documents is critical to providing a quality user experience in today’s applications. Without some way of controlling the presentation of digital files like PDFs, organizations put themselves in a situation where they must rely on external solutions that may not be responsive to their needs. PDF integration into their applications helps developers to maintain control over their documents while providing a more consistent viewing experience for users.

What Are Your PDF Reader Options?

Sharing and viewing PDFs online has become much easier with the development of HTML5 viewing technology and PDF.js-based software. For many years, the only way to view a PDF was to download a file and open it using a dedicated PDF reader application. Although many of these readers could be added to a web browser using a plug-in, this wasn’t always a reliable solution and inconsistent support for these extensions often created security risks.

After Mozilla introduced the PDF.js open-source library in 2011, integrated PDF viewing quickly became an essential feature for web browsers. Most users now simply take PDF viewing for granted, trusting that their browser will be able to open and read any file. For some organizations, relying on a browser PDF reader is a perfectly reasonable solution, especially if they don’t have any concerns over controlling the document viewing experience.

But for many developers building web applications, these browsers and external PDF readers put them at the mercy of third-party providers. Changes or security problems with these solutions can leave development teams scrambling to implement workarounds that could have been avoided if they had their own dedicated viewing solution. That’s why applications increasingly feature a built-in PDF reader that allows them to better manage and present important digital documents.

Why Your Application Needs a Built-in PDF Reader

The core problem with relying on an external viewing solution comes down to control. In order to view a PDF in a dedicated reader, the file needs to be downloaded. Once that document is removed from a secure application, it could easily be distributed or altered without any authorization or oversight. This often results in serious version confusion that leaves everyone wondering which version of a PDF is the most up-to-date. By keeping documents within a controlled application, developers can ensure that the files viewed there are current.

Relying on external PDF viewers can also create an inconsistent user experience. Since not all viewers render documents, in the same way, it’s impossible to control what someone will see when they open a given PDF. In some cases, that could result in wrong fonts being displayed or some image layers failing to render properly. But it may also prevent someone from even viewing a file at all. For example, browser-based viewers that use the base PDF.js library without making any improvements to it often struggle to render lengthy or complex files. 

When applications incorporate a built-in PDF reader, developers can ensure that every document viewed within that solution will look the same on every device (and that it will open in the first place!). This level of control is incredibly important for organizations looking to build a frictionless and compelling user experience.

Integrating a PDF Reader

By incorporating a PDF reader into their web-based applications, developers are able to both retain full control over the viewing experience and keep files within a protected environment. When users are interacting with the application, all PDF viewing can be handled by the built-in viewer rather than handed off to external software. This makes it easier to manage access effectively and limits the number of downloads. 

Since every user will be viewing documents through the same built-in PDF reader, developers can also craft a consistent experience across multiple platforms. With more and more people accessing their applications with mobile devices, it’s important for development teams to offer responsive viewing solutions that can accommodate various screen sizes and interfaces.

In order to maintain complete control over files and deliver better performance, a built-in PDF reader should be able to operate as an entirely client-side solution. Whether it’s running within an on-premises technology stack or as part of an application’s cloud deployment, a PDF viewer without any complicated dependencies never has to worry about connecting to a third-party service to facilitate viewing. 

But why stop at PDF viewing?

PDF Editing

Often users need the ability to view as well as collaborate on their PDF documents, and providing the ability to edit those documents presents a challenge for developers. In a recent survey conducted amongst developers, there appears to be a disconnect between the PDF editing features that are available in most applications, to what developers actually need to fulfill and enhance their applications. So what’s the solution? 

Third-party Integrated PDF Viewing and Editing

A PDF solution provider has already worked out the challenges associated with viewing and editing PDF documents within an application. They’ve also devoted their resources to improving their document capabilities and expanding features to offer greater flexibility.

A good third-party provider also offers extensive support during and after the implementation process. If the developer needs to add a new PDF-related capability to their application or if they encounter a problem, they can quickly resolve the issue by working with their provider rather than wasting valuable resources trying to identify and fix the problem themselves. That combination of expertise and service means that developers can spend more time focusing on their application’s unique features rather than continuously wrestling with PDF-related challenges.

Security is everything for organizations when it comes to their sensitive data assets. Whether it’s vital documents, account passwords, or proprietary financial formulas, essential business information needs to be well-protected as companies continue to incorporate digital platforms into their operations. Developers can support this critical goal by providing secure digital vault applications that allow their customers to manage and use information assets without exposing them to unnecessary risks.

The heightened emphasis on security has made digital vault services quite popular in recent years. In order to maximize the potential of these security platforms, however, developers must integrate the right tools for managing multiple file types ranging from standard documents to complex financial spreadsheets.

What is a Digital Vault?

Much like its physical counterpart, a digital vault is a secure repository for storing vital assets in one easy-to-manage and fully-encrypted location. In some respects, these platforms are similar to information management services or cloud-based storage, but they set themselves apart by emphasizing security and access control. Digital vaults are frequently used for estate planning thanks to their ability to securely store account log-in information and vital documents, but they’re also popular with high-net worth individuals and organizations that need a safe place for sensitive financial data.

The core feature of a digital vault is its ability to prevent unauthorized access to materials stored inside them. They do this by strictly monitoring access rights at multiple levels. Just because someone has access to the vault itself, for instance, doesn’t mean they have access to everything it contains. The files and documents stored within the digital vault can all be set with their own access permissions. These controls mirror those used in a physical bank vault, such as:

• Requiring manual authorization from an administrator to access data.
• Implementing dual key control mechanisms.
• Limiting access to certain times of day.
• Segmenting access to relevant assets only.

Managing Digital Vault Information

Digital vaults also make the process of managing data much more secure. Since all of the assets stored within the vault are protected by encryption, they can be shared through a portal rather than downloaded, copied, or transmitted over poorly secured channels like email. The data itself never leaves the protective confines of the vault, and the security controls track who has been granted access when files are shared. This makes it easy to monitor activity and ensure that confidential files are not broadly distributed.

In order to facilitate this access, however, digital vault developers need to build viewing and editing tools into their applications. Without the ability to open and view a document within the web-based portal, for instance, users will be forced to rely on external software. This defeats the whole purpose of a digital vault, as it exposes the file to whatever security vulnerabilities that application might possess.

Integrating HTML5 viewing capabilities into their vault’s web portal allows developers to let their customers review documents and even make annotation markups without having to remove the file from a secure, encrypted environment. For most documents and images, this is a relatively straightforward process using a series of API calls to render the file within the browser.

The Challenge of Excel Spreadsheets

Microsoft Excel spreadsheets, however, frequently pose a major challenge to digital vault platforms. Unlike documents, spreadsheets are often designed to be interactive and can contain sensitive financial calculations within cell fields. Simply sharing a static, print preview image of a spreadsheet might be helpful for reviewing financial records, but it’s not very useful to someone who needs to enter fresh data into the formulas to calculate new results.

While the XLSX file could be made available for download to anyone who is authorized to use it, this defeats the purpose of having it stored in a digital vault. Not only would it be impossible to track the downloaded file, which creates serious data security risks, but allowing multiple copies of the file to proliferate will quickly lead to version confusion.

Enhancing Spreadsheet Functionality with PrizmDoc Cells

Digital vault developers can easily solve their spreadsheet challenges by integrating Accusoft’s PrizmDoc Cells into their application. A completely web-based spreadsheet viewer and editor, PrizmDoc Cells provides native XLSX file support without any external dependencies. The API-based integration allows users to open their existing Excel files to view, edit, and add comments completely within the application’s web portal. PrizmDoc Cells provides a familiar interface that developers can customize to meet the specific needs of their customers.

That same customization extends to the spreadsheet elements themselves. A digital vault provider may not want to allow users to have full access to every element of an Excel file. For instance, an organization may be fine with allowing someone to enter new data and calculate results in the spreadsheet, but not want anyone to be able to view the proprietary formulas buried within the cell fields. When integrating PrizmDoc Cells, developers can control what aspects of the XLSX file are actually shared. This makes it easy to keep formulas and other data locked in place within the spreadsheet and secure from unauthorized viewing.

Few document formats are more common than XLSX spreadsheet files. Although many alternatives are available, most enterprises continue to rely on the broad (and familiar) functionality of Microsoft Excel when it comes to their spreadsheet needs. However, few organizations take the appropriate steps to ensure Excel spreadsheet security, which could leave their private data and formula assets exposed to substantial risk.

As a third party dependency, Excel represents an obvious security gap that could easily be exploited. Any time a file travels outside a secure application environment, there is a potential risk of data theft and version confusion. In any situation where files are travelling between separate applications, there is also an opportunity for malicious files to slip into unsuspecting workflows. By focusing on ways to shore up their Excel spreadsheet security, organizations can minimize risk and protect their sensitive data.

Excel Spreadsheet Security Risk #1: Malicious File Extensions

Most organizations are aware that opening a file attached to an email is one of the most common ways to introduce malware into a system. What they may not realize, however, is just how pervasive the problem is or how well those files are masked. It’s easy to identify a malicious email attachment when its name is a jumble of letters and it has an unfamiliar file extension. The real threat comes when it actually resembles something familiar and potentially legitimate.

Unfortunately, XLSX spreadsheet files are frequently used to distribute malware. According to a comprehensive cybersecurity study conducted by Cisco in 2018, Microsoft Office file extensions (such as DOCX and XLSX) were used by 38 percent of malicious email attachments, higher than any other format. These extensions are attractive to cybercriminals precisely because they’re so widely used. Someone working in a financial services organization, for instance, is usually quite accustomed to sending and receiving spreadsheets via email, so they are more likely to open an XLSX file out of curiosity.

Of course, this raises a separate question about basic cybersecurity. No organization today should be relying on poorly secured channels like email to share sensitive documents in the first place. By integrating native XLSX viewing and editing capabilities directly into their web applications, developers can provide the tools necessary to share spreadsheets without the risk of exposing collaborators to malicious file extensions. Embedding spreadsheet files into the application allows for easy access, but also keeps the file safely within a secure environment. Once users become accustomed to accessing spreadsheets this way, they’ll be less likely to fall prey to a malicious XLSX extension in their email. 

Excel Spreadsheet Security Risk #2: Insufficient Access Control

Spreadsheets can contain a great deal of information. Not only do they make it easy to reference data and carry out complex calculations in seconds, there’s a lot happening behind the scenes that may not be immediately obvious to the average user. Spreadsheet cells typically incorporate highly detailed (and often proprietary) formulas that help organizations to estimate costs, assess risk, and adjust revenue forecasts. For many industries, there’s simply no software that can compete with the extensive capabilities of spreadsheets.

But that versatility comes with a cost. Any user with a rudimentary knowledge of spreadsheets can easily reveal hidden information and examine the formulas behind the document’s calculations. And once they’ve downloaded their own copy of the spreadsheet, there’s nothing to prevent them from using it elsewhere, which can be a serious problem for any organization that depends upon its proprietary formulas to drive business success.

The root problem in this case comes down to who has control over the spreadsheet. When an XLSX file is shared, it can then be copied or even altered without the knowledge or permission of its original owner. The best way to maintain control over spreadsheets is to integrate native XLSX viewing capabilities directly into a web application. This allows developers to control which elements of the spreadsheet are being shared and prevents anyone from downloading a copy without permission. Since users can only interact with the spreadsheet on the terms set by the file’s owner, they can’t peek “under the hood” to obtain proprietary assets like cell formulas.

Secure Your Spreadsheets with PrizmDoc Cells

Accusoft’s PrizmDoc Cells is a powerful API integration that allows developers to provide dynamic spreadsheet viewing and editing capabilities within their web application environment. Far more versatile than traditional viewer integrations that offer only a static “print preview” image of a spreadsheet, PrizmDoc Cells makes it possible to scroll both vertically and horizontally and even enter information into cells to perform calculations. It’s the most secure way to provide access to spreadsheet resources without sacrificing control over editing permissions. And since the XLSX file never has to travel beyond a secure application environment, there’s no need to worry about malicious file extensions when sharing spreadsheets.

Developers can use PrizmDoc Cells’s whitelabeling features to customize its look and functionality within their application. From editing cell content and format to embedding graphics, they retain complete control over the way viewers interact with spreadsheet files to maximize security and protect vital proprietary information.

Spreadsheets remain a standard tool for many organizations, and despite increasing adoption across cell-based competitors such as Google Sheets, Excel still owns the market. As noted by research firm Robert Half, while the use of XLSX formats is on a slow decline, almost 70 percent of finance firms say Excel remains their spreadsheet software of choice.

Fundamentally, this comes down to familiarity; 62 percent of users surveyed find this common format easy to use, making it their go-to option when entering financial data or performing quick calculations. The only problem with this is that this spreadsheet tool introduces significant security issues. According to recent Cisco data, 38 percent of the most prevalent, malicious file extensions use Microsoft Office file formats — including Word, PowerPoint, and Excel — to compromise corporate networks.

Accusoft is now offering a more secure, web-based solution for spreadsheet needs. PrizmDoc Cells offers a web-based spreadsheet viewing and editing alternative that makes it possible for independent software vendors (ISVs) to easily incorporate XLSX functions into corporate applications without increasing security risk. Here’s how the newest part of the PrizmDoc Suite can help companies streamline processes while maintaining security.

Web-Based Spreadsheet Security

Common spreadsheet practices come with significant risk. As noted by ZDNet, for example, a new malware group is using the Excel file format that creates malicious spreadsheets that bypass security scanners and — thanks in large part to their format familiarity — are opened by end-users. This creates a self-sustaining problem. With single-source spreadsheets still the norm for many financial firms, attackers just need to spoof corporate email addresses and attach familiar XLSX files to compromise corporate networks.

For ISVs, this presents an opportunity. The market needs a secure way to view and edit spreadsheets in-browser and they need to be able to control the way the formulas are viewed and manipulated. By delivering browser-based spreadsheet viewers and editors within their own applications, ISVs can streamline their clients’ processes while maintaining security and controlling data sharing. PrizmDoc Cells integrates with ISV’s applications to enable easy spreadsheet viewing and editing functions. This integration allows administrators to lock down spreadsheet access by making them read-only or disallowing downloads, while also permitting protected sharing so that users can perform calculations without compromising the original source.

Value-Added Version Control

Collaboration is critical for effective spreadsheet use, especially among highly regulated industries like finance. From sharing key data around lending, credit, or investment applications to completing profit and loss calculations, spreadsheets remain a staple of efficient and effective financial transactions.

As with any industry, version control is a challenge for any third-party file collaboration. As noted by Beta News, the still-popular process of downloading spreadsheets to end-user devices comes with multiple versioning issues, including:

• Loss of Visibility — When files are downloaded onto end-user devices, information security teams naturally lose sight of how information is used, changed, or shared. Not only does this make it impossible to deliver consistent version control, but it puts organizations at risk of regulatory non-compliance.
• Data Discrepancies — Once data is downloaded, it is instantly out-of-date. Replicated across multiple users, this scenario creates substantial subsets of data that are all slightly different and require significant analytical effort to create some semblance of reliable version control.

When an ISV integrates PrizmDoc Cells within their application, the functionality reduces version control challenges by allowing spreadsheet owners to remove visibility into underlying logic, such as proprietary business formulas or calculations, as required. It also eliminates the need for client-side installs or downloads, which adds another level of security for comprehensive version control.

Reducing Human Error in Spreadsheets

Errors remain a common spreadsheet concern. As noted by Computer Weekly, “Several research studies have found that up to 70% of spreadsheets contain errors which would result in serious miscalculations.” This creates both productivity and security risks. If calculations create inaccurate outputs, organizations may find themselves struggling to find the source of equation issues or computation concerns. If the problem persists, staff may share the affected spreadsheet in hopes of quickly finding a resolution, in turn potentially exposing documents to increased risk.

PrizmDoc Cells solves this problem with browser-based spreadsheet viewing and editing functionalities. Files display as they would in native applications but can be embedded across any website, CMS, intranet, or portal, allowing staff to securely view and manipulate spreadsheets based on permissions. While it’s impossible to eliminate the potential for formula or format issues, it’s imperative to keep data safe in a secure environment, and sharing these spreadsheets securely makes finding and solving any error more efficient.

A Secure Browser-Based Spreadsheet & XLSX Integration

Excel-based spreadsheets cannot stand up to the security and data sharing needs that companies need to scale. When it comes to sharing sensitive data and manipulating formulas, there is both complexity and corporate risk. Without the right permissions and controls in place, data could easily be misrepresented, costing the company revenue.

With PrizmDoc Cells, ISVs can provide the capabilities end-users need for secure spreadsheet viewing and editing. With the ability to independently import, edit, and export XLSX files, securely embed spreadsheet data anywhere, reduce error rates with secure collaboration, and streamline version control, it’s worth opening the door to new spreadsheets capabilities.
