Google Sheet file history store memory

Problem

You want to know how far back the revision history in Sheets is stored.

Environment

  • Google Drive
  • Google Sheets

Solution

  1. For Non-Google Files, they may be deleted after 30 days or after 100 versions are stored. 
  2. For Google Files, there is no limit mentioned to how far back the Version History is. However, Google Sheets may optimize the storage space by either merging some older versions or deleting some of the oldest changes if your Google Drive memory is close to full.
