Excel intergration?

Can you please tell us a bit more details in regards to your query?

Since you say Excel, I presume that you would like to have the data saved from the form to an Excel file. If so, that is quite easy since you can grab one from your Submissions Panel: How to Export Form Data to Excel? or simply user Excel report if you want to fine tune the data that you wish to get: How to create an Excel Report?

Since you mention integration as well, I presume that you are thinking of a way to have your Excel file updated on each submission, in which case the closest option would be: Reports To Cloud integration that you could use.

If you give us a bit more details on what you would like to accomplish, we would be able to help you with a closer match of what you are after.

Unfortunately it is not possible to import the data from your Excel file into your form and use it as inventory. You can only add it manually into the widget / field that you use.
