Sweet baby Jesus, I was able to restore the tables from the archive tab. My panic attack is gone.
For anyone else who is in this predicament:
If a user has their account structured like this:
Folder
then performs the following action
Folder
Table 1 → Convert to Workbook 1
Table 2 → Convert to Workbook 1
Table 3 → Convert to Workbook 1
The account will look like this:
Folder (empty)
Workbook 1
If you delete the empty Folder, you will have mild panic attack because Workbook 1 will be empty.
The fix:
Click the Archive on the top right, and you’ll see that all those files in the empty folder are deleted from the Workbook. Restore 1 by 1 and they will appear in the Workbook, as expected.
