Microsoft 365 PDF Accessibility
Article• 11/26/2024
Microsoft 365 Apps for Windows including Word, Excel, and PowerPoint allow users to
export documents in PDF format. Furthermore, add-ins can use the object model to
automate PDF export using either the exporter built in to each app or their own exporter
that implements the IMsoDocExporter COM interface.
An important part of exporting to PDF is writing PDF/UA  tags that provide the
semantic information to preserve the accessibility of the content. This allows people with
disabilities to consume the PDF using assistive technologies such as screen readers. This
documentation provides details about the PDF/UA tags written by the exporter built in
to Word, Excel, and PowerPoint as well as the APIs that add-ins need to implement to
provide their own exporter.
