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.
While Excel file can not be uploaded and shown on the form, you could use the Spreadsheet widget to achieve similar effect, or alternatively use our Iframe Embed widget to show Google Spreadsheet right on your form.
If you can tell us what you would like to achieve we would be happy to assist you and recommend the best way to achieve the same.
