Monthly reports in Excel will not save

[Lional43]

I am using Microsoft 365 Excel. I need to make a copy to keep formatting but change my values. I do monthly reports. In the older installed version, it didn't save to the Cloud. When I make a copy and changes, it changes the original file too. Please help.
