Users may sometimes need to revert back to a previous version of a binder. This can be done as follows:
​
​
1. Open the workbook in Excel and save a copy as a backup.

2. Open a fresh copy of the binder in Excel, navigate to File > Info, and select 'Open file location.'

3. This action should open a new browser window with the SharePoint location. Click the three dots next to the file and access version history.

4. Click into an older version of the workbook. This should open that version in excel. Once opened, follow the on-screen prompts to restore this previous version of the workbook. Ensure the add-in is functioning properly.

5. Close and reopen to retest.
