Why are some Excel files opening as PDF?

Body

The maximum file size that a document can open in the Microsoft Excel Online Viewer is 25 MB.

When attempting to view spreadsheets larger than 25MB, you are prompted to use the Datasite document viewer and view the file in PDF form.

Additional file features that are not supported in the Excel Online viewer include:

  • Files created in Microsoft Office 95
  • Files with macros
  • Files with cell watches enabled

Attempting to open files with these attributes prompts messaging directing the user to view the item as a PDF.
