Accessible Office Documents

Microsoft Office products generally have powerful accessibility tools built into them. Microsoft software that is installed on a computer may have a different (and usually broader) set of tools that online Microsoft tools like those in Office 365.

Below are some best practices for accessibility in Microsoft Office documents, especially as it pertains to writing math. Many of these best practices also work for the OpenOffice and LibreOffice suite of tools.

Best Practices


  • Add alt text to all images
    • Right click the image (or a non-text object)
    • Select View Alt Text... from the context menu (sometimes called Edit Alt Text...)
    • Enter the image description in the box. Microsoft Office may offer to generate a description for you; if you use this feature, be sure to review and edit it.
    • If the image is purely decorative you can check the Mark as decorative checkbox, if available. If that option is not available you can simply use "decorative" as the alt text.
  • Use semantic markup to structure the content. More precisely, label each part of the document as something like "Normal", "Paragraph", "Heading 1", "Heading 2", etc. There is usually a dropdown menu at thte top of the application with these options.
  • Use informative link text for any hyperlinks in your document
  • Follow the two main rules when using colors:
  • Use built-in list creators for numbered and bulleted lists. These are usually found in the toolbar at the top of the application.
  • If you include tables make sure it has header rows

 

Math Equations in Word and PowerPoint


To better meet accessibility requirements when writing math equations in your document

  • Use the built in Equation Editor (not screenshots)
  • Add alt text for plots, graphs, and diagrams
  • Run the Accessibility Checker
  • It is better not to export to PDF, instead export to the native file format (usually .docx or .pptx)

 

Accessibility Checker


The following is taken from Yao-Yuan Mao's page on accessibility in documents and slides from Office applications:

Microsoft Office and OpenOffice/LibreOffice both offer built-in accessibility checkers that can help you check that you have applied the accessibility features correctly and identify any potential issues. To use the accessibility checker:

  1. Go to the Review tab (in Microsoft Office) or the Tools menu (in OpenOffice/LibreOffice) and click Check Accessibility (or Accessibility Check).

  2. Follow the prompts to review any accessibility issues identified by the checker and make necessary adjustments to your document.

Google Docs/Slides and Apple’s iWork suite of applications (Pages, Keynote) do not have a built-in accessibility checker unfortunately. If you want to use a checker, you can download the document and then use Microsoft Office or OpenOffice/LibreOffice’s accessibility checker.
