Tech Bits: Remove Hidden Information in Office Files


Tuesday, March 12, 2019

Did you know that the Office documents you create contain hidden data?

Examples of hidden or personal information that are stored in Word, PowerPoint and Excel documents include:

  • Tracked changes, comments, annotations, and versions, even if not displayed
  • Hidden text or data cells
  • Presentation notes
  • Previously deleted text
  • Name of author and person who last modified the file

If this sensitive “hidden” information became public, you could find yourself in an uncomfortable situation. To avoid this, make sure that any review comments and hidden information are removed. To learn how, see Removing Hidden Information from Microsoft Office Files.
