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.
To integrate Google Spreadsheet with your form please refer to this simple guide - How-to-Integrate-Form-with-Google-Spreadsheet.
If what you need to integrate is Google Docs, unfortunately we do not have Docs integration.
You could integrate Google Drive to get something similar to what you might want to have with Docs. Each submission will be saved as a PDF file in your Drive account along with uploaded files if any.
Do let us know if more assistance is needed.
