I've tried using Google Sheets but it can't manage simple mailing labels that Excel has been able to do for the past 30 years. In Google sheets, you need to sign up for a monthly subscription plugin to get that feature.
Yeah I kinda gave up with Google for label printing, I use the app for my thermal label printer along with a CSV file if I need to print a batch of them..
I think the last version I bought was 2003 student edition- which anyone could buy because didn't need online registration with a student email.
I did sign up for office 365 to help my wife with some vba scripts. It's insidious because you can turn the subscription on and off but forget to turn it off.
