I have upvoted this request to share a spreadsheet public but in live mode, basically I need the same but the other way around.
I need to be able to share a spreadsheet privately but in edit mode, so the user that clicks the url is asked to duplicate the spreadsheet into their own account, so the work on their own data, and not mine.
Basically its what Google Sheet does.
This would also bring in more users I guess if they have to create an account to use the spreadsheet they have received a share link for.
Now I don’t know if you still use the hellonext feedback system, so this is why I mention it here in the forum as well.
