This is the line in my code: ActiveWorkbook.SaveAs Filename:=curPath & cell.Value & Format(Now, "dmmmyyyy" & ".xlsx"), FileFormat:=xlOpenXMLWorkbook, CreateBackup:=False
Here's the extension from a couple of the files: .xl47x .xl35x
I tried using ".xlsm" and I got: .xl78 .xl22
I can force change the name and then the file will open - but why is it changing the extension? Does someone know what is going on? I've never seen this. Thank you!
