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're trying to provide the Excel file to your submitter then you can simply include it in an email auto-responder.
While you're creating your email auto-responder click on the "Advanced" tab and add your attachment there.
But do note that this cannot be password protected, it will be send to anyone who submitted your form.
You may also add the link to your spreadsheet in your form and ask for something to show the field link, but, please avoid using words such as password, passcode, or access code since asking for this info is not allowed at JotForm and your will be suspended.
This guide will help you to show / hide fields or text based on another field input:How-to-Show-or-Hide-Fields-Base-on-User-s-Answer
