Is there a way to download all my Revision History as .doc documents from Google Docs (.xls from Google Sheets and PPT maybe from Slides)?
Unfortunately, it does not appear possible to download individual revisions of Google Docs, Sheets, or Slides without going in and reverting a file to each separate revision and downloading it normally. I did some investigation into Google Apps Script and the Google Drive REST API; Apps Script has no access to revision history, and the REST API does not seem offer the ability to export the contents of a revision to a file.
This does not apply to files of non-Google formats, such as Word documents, audio files, and images. As long as a version is still saved on your Drive, you can go into the "Manage versions..." dialog and download each saved version of a file.
Now it's possible to make a copy of each version. To do that, do the following
- Press Ctrl + Alt + Shift + H
- Locate the desired version, then click the three dots button, then Make a copy. A Make a copy dialog will show up.
- Change the options as necessary, then click OK
