What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
If you would like to remove the data from the Google Spreadsheet that is still integrated to your form, you should be able to simply remove the data in your Submissions Panel, which should result in the same data being removed from the Google Spreadsheet.
If that is not what you meant, please do let us know.
