Thanks for checking. I asked ChatGPT3.5 to make a solution with excel since I have limited access to it at work. CG came up with making my data a table with Power Query & using a Fill tool, but Fill>Down isn’t doing what CG is saying it’s supposed to do.
I hope I could do this at home though because I only have Onlyoffice & Libreoffice, & excel in the browser is so limited.
