For background, when I set up my app I failed to use a Google sheet with several tabs so I ended up with the main green sheet and a bunch of black ones in the nav bar. I guess they are Glide sheets now.
Changing out the Google sheet is something I can do, but wonder how to replace the existing data in the others without wrecking all the Relation and Row Owner columns I have set up.
I don’t want to try to import something and have it mess things up if there are no options to keep those related columns and start with fresh new data. Any suggestions?
