Upload information to auto populate in drop down menus

If I have an excel document that has multiple columns of data, am I able to upload it to a jotform so that it exists on the jotform in the backend. So I can use that data to populate when choosing drop down menus?

I think what you're trying to create is related to the Spreadsheet to Form widget. Here's a guide and you can also check the demo form on this link: https://www.jotform.com/help/442-How-to-Use-the-Spreadsheet-to-Form-Widget

Please try it and let us know if that's not what you're looking for.

Thank you.
