How to link attachment using URL

How to attach external table using URL to the form?
I know we can upload csv as file to generate drop down, etc but wanted to find out how this can be done using URL file. Please help!.

Welcome to the community, @Diluksion! Could you explain more about the URL file you are trying to refer to? The community could then help you out if it’s possible with KoboToolbox.

I was trying to use the values from external file(excel) for drop down by attaching the csv file in the media. I also realize that there is an option to attach the file using URL and I wanted to check how that can be done.

I’ve tried copying URL file but it didn’t worked out.

Let me know if there are any ways that I should follow…

Is the URL attachment only to attach images?
