Here is the context of this question. We used Google Forms for an election of 6 people. I want to know if it is possible to delete individual responses and then recover all responses (deleted and not deleted). For example, on Google Docs you can look at everyone's edits and recover deleted items from previous dates. Is this possible with Google Forms and if so, how can I get all of this information.
If you didn't save the form responses to a Sheet before deleting them, they cannot be recovered after deletion.
I contacted Google support about this issue in the past and they told me the same thing - they don't have an undelete button for Forms.
