Submitting a xls via Coda/Email Automation

Hi everyone,

As part of out onboarding for out tool, we ask customers to fill out a template xls and to then send it back to us.

In Coda, I link to the Gsheet which is view only (they’d nee dto copy it to edit or they can download a xls version to fill out). They then need to send it back to us.

Is there a way to have them upload the completed xls directly into Coda or perhaps automate an email where they can attach it?

Thanks!
