How to use the Spreadsheet to form widget?

Is there any tutorial for this widget. I don't understand how to use it.

Yes, please check this guide to get more  details about how to use it: https://www.jotform.com/help/442-How-to-Use-the-Spreadsheet-to-Form-Widget 

If you have any other question, please let us know, we will be glad to help you. 

Thanks. I realized that this is not what I am looking for. I need a widget that will convert an excel spreadsheet into a web form. I do not need to populate a form with data from a spreadsheet.

Unfortunately, it's not possible to achieve, you can only import submissions from a spreadsheet, but it's not currently possible to import a form from a spreadsheet.
