Insights about Accessibility

The all-in-one solution for creating compliant documents in Microsoft Word, PowerPoint, and Excel

In Microsoft PowerPoint, Accessibility Assistant processes PDFs using a separate engine that tags all content following the PDF/UA format (also known as ISO 14289). This includes elements such as images, tables, charts, placeholders, headings, lists, and hyperlinks.

In Microsoft Word, Accessibility Assistant exports PDFs using the native Microsoft 365 PDF tagging engine. This engine is enhanced with several post processors to restructure and recreate tags for almost every content element, ensuring that the resulting PDF is fully PDF/UA compliant.

In Microsoft Excel, Accessibility Assistant works the same way as Word. The exporting process employs the native Microsoft 365 PDF tagging engine and undergoes post-processing. In addition to the same checks performed by Word, Excel includes an extra check that detects when a shape spans across pages. Our software notifies the user to relocate the shape within the confines of a single page to ensure it doesn’t cross over.

Accessibility Assistant is constantly developed to be fully compatible with Microsoft 365, and it also supports versions 2010, 2013, and 2016.

In addition to PDF/UA compliance, Accessibility Assistant also audits and checks for WCAG 2.2 compliance and the inclusion of embedded fonts (for PDF/UA compliance) in Microsoft Word documents.”
