How do I extract the information from submissions into an excel spreadsheet?

Hi,

This guide should help you on how to export your form submissions into an excel file: http://www.jotform.com/help/44-How-to-Export-Form-Data-to-Excel.

Or, you can create a report so you can filter what fields to include in the excel file: http://www.jotform.com/help/101-How-to-create-an-Excel-Report 

Thank you!
