Apryse WebViewer SDK release notes

v11.6.0
In this release, we’ve extended editing and layout controls for DOCX Editor and Spreadsheet Editor, both add-ons to the Web SDK, bringing more sophisticated formatting, styling, and cell-level control into a single, browser-based experience. It’s a step forward in keeping users focused and productive within your application.

Our modular UI now meets WCAG 2.2 AA standards across WebViewer, DOCX Editor, and Spreadsheet Editor. This ensures your applications are accessible to users with motor or visual impairments, without requiring additional development effort.

The Spreadsheet Editor interface uses an Excel-like layout users are used to seeing so it’s intuitive and easy to use. Building on our View Mode launch, Spreadsheet Editor now has edit mode functionality users can use for:

• Cell Formatting: Modify text size and color, fonts, border styles, cell colors, border colors, and text styling for bold, italic, underline, and strikethrough.
• Formula and Function Support: Execute standard mathematical operations, statistical calculations, date/time functions, and other common formulas.
• Dynamic Data Manipulation: Easily add, edit, and delete rows and columns. Seamlessly cut, copy, and paste data.
• Cell Adjustments: Merge cells and preserve formatting.
• File Support: Open and export files in .xlsx format.

Editing capabilities in Spreadsheet Editor reduce reliance on third-party systems, multiple vendors, and file downloads for everyday spreadsheet tasks without compromising control, compliance, or security. Teams can format and calculate spreadsheet data directly all with a similar look and feel to how they manipulate PDFs and DOCX files.

See the following new documentation for developing these features:

• Spreadsheet Editor overview guide
• Spreadsheet Editor basic setup guide
• Spreadsheet Editor view mode guide
• Spreadsheet Editor edit mode guide

DOCX Editor now has a new layout tab users can use for:

• Margin Editing: Adjust the top, bottom, left, and right margins of a document’s body on a section-by-section basis. The Margin menu offers standard preset values, and you can also set custom values within it.
• Column Page Layout Editing: Adjust the number of columns and their width and spacing. You can apply the configurations you set to each section. You can also set uneven columns through custom settings.

Now, you can make more complex documents that jump from one section to the next with different layouts. DOCX Editor preserves text flow and section logic to ensure documents remain true to their original form, no matter how complex the layout.

The benefits of margin and column editing include:

• Professional formatting and branding across documents, from proposals to reports.
• Compliance with legal and industry standards, especially for industries like legal, education, and government that often have strict formatting guidelines.
• Text that isn’t cramped and enough white space around content, improving overall readability.
• More balanced, organized document layout.
  

DOCX Editor eliminates dependency on using other apps and file downloads without compromising security, control, or compliance. Companies can format and write directly within the same interface they’re already using for PDF files.

Our modular UI now meets WCAG 2.2 AA standards across WebViewer PDF Editor, DOCX Editor, and Spreadsheet Editor which ensures your applications are accessible to those with motor impairments, visual limitations, or cognitive disabilities without requiring additional development effort.

Here’s everything you get for a consistent, accessible UI with default behavior that enables developers to embed accessible in-browser document experiences without needing to build a custom solution from scratch:

On June 28, 2025, The European Accessibility Act made effective the requirement that digital products and services comply with WCAG 2.1 AA standards for certain industries. Our accessibility update exceeds the WCAG 2.1 AA baseline.

We recommend that customers review their usage of our Web SDK solutions to ensure that their own applications remain compliant. Product and accessibility teams should test against the updated criteria and are encouraged to contact us with any questions or concerns.
