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.
Yes you can get back deleted form Responses
i know this is an old post but this answer is for anyone else looking for the same solution to a similar problem quite recently.
You might have some luck here- google has quite a good auto backup system when it comes to sheets
Login on your desktop browser for easier access
Your form responses are generally linked to a google sheet someplace - if you want to know which sheet name click on the green sheet logo on the right hand top corner of your google form settings - it will ask you if you want to change the location of your responses "dont click anything " just make note of the sheet name that you see auto populated there.
Go to your google sheets in your google drive account & select that sheet that your form is linked to.
Click on "file" on the Menue
Click on "Version History > See Version History "
let it load
on the right hand side of the page you will see the diffrent auto saves done by google sheets - it includes everything that was inputed onto the google sheets -all data including that of the form, since the last time you accessed it.
Just tick the option "see changes" you will see all the changes done across the sheet in each and every timestamped version.
when you found what you looking for -clcik on "restore this version" get the data you need or deleted etc - it will all be saved here
take note this will restore your sheet back to the version you have selected based on the date & time of that auto backup you selected
