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.
I am not quite sure if I understand your concern correctly. Would you like to have a table excel displayed in your form or you want the submission data to be on a spreadsheet? We have a "Spreadsheet" widget that allows your users to have an excel like data input on your live form, although it does have its limitations.
You can also directly save your submissions in your Google spreadsheet by doing an integration. Here's a guide about it: http://www.jotform.com/help/228-How-to-Integrate-Form-with-Google-Spreadsheet
Let us know if that if your concern is different from the suggestions I have.
