Nextcloud Integration Question

Can someone expand on the capabilities of the Nextcloud integration?
A use case we regularly use with Google Sheets is to send submissions form a form into a new row of a spreadsheet. We would like to start using Nextcloud for this.
I see that it would likely require two nodes - Nextcloud for connecting to the file in question and then write to the latter row of the excel spreadsheet. Has anyone accomplished this in the past?

Though I haven’t tried it this is possible using the Execute node and a custom script to edit .xlsx files via command line then reupload it using a Nextcloud node

Is actually quite easily possible without any command line tools.

I created an example workflow here:


Many thanks, can’t wait to try this out!
