How to Delete the Revision History in Google Docs
Google Docs is an online word processing platform for your Internet browser, giving you the ability to create text documents, presentation slides and spreadsheets in a similar way to the programs in Microsoft Office. These files are stored within your private Google account, so you can access them by logging in with your username and password, then share them with selected users. The platform tracks all revisions made to your documents, but you can delete this revision history with just a few clicks.
Log in to your Google account and click the "Documents" tab to access your files.
Click the file for which you want to remove the revision history. The file opens in a new editing window.
Click the "File" button in the document window (not in the main browser "File" option).
Select "Make a Copy" and click "OK." The new copy opens in a new browser tab.
Return to your Google Docs homepage. Mouse over the original file and click the "Actions" button. Click "Move to Trash" to remove the file.
Click the "Actions" button for the copied file. Click "Rename" and remove the "Copy of" text from the title. Now you have a complete copy of the file with the exact same title as the original. When you access the revision history for this copied file, it will show only the creation of the copy and none of the revisions made to the original file.
