JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
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.
Have you made any modifications directly to the Google Spreadsheet? Please note that modifying the spreadsheet can cause the integration to break.
To resolve this issue, you will need to remove the current integration. Once you have removed it, you can then re-integrate your jotform with google sheets. Please note that this will create a new spreadsheet, so you will not be able to connect to the previous one. The new spreadsheet should have all the previous data and all the new data that you may receive.
If the issue persists, please let us know.
