The forms I'm working with have had the Automatic Timestamp removed and thus that info is not showing up in the Excel export. I'd like to confirm that I'm understanding the previous thread correct that there is, indeed, no way to re-add the Automatic Timestamp to an existing Form. Thanks!
@Mozan502 no you can't re-add the timestamp. Just something for you to consider for the future but in my company we ALWAYS save each response to a list in SharePoint via a flow in Power Auotmate. That way we always have a backup and the created column will have the date/time the response was submitted/item created and it doesn't rely on the Excel spreadsheet.
