Attachment Validation or Record Producer/Catalog Item

[Prathamjeet Sin]

I have a form with a mandatory field requiring users to upload an Excel (.xlsx) file. Is there a way to prevent users from uploading incorrect file types, ensuring they only submit .xlsx files either in the form view or prior to submission?
Thanks in advance for any assistance.

A way to go might be applying the variable type "attachment" and specifying the allowed types in the attributes field. For example:

allowed_extensions=xlsx

When selecting an incorrect type, it will automatically show:
