Excel 365 macro creating workbook in Compatibility Mode

[patbuk]

Hello,

I am at a loss. I created an Excel vba macro in 365 on one of my PCs (both have Office 365 and also Excel 2010 on them) and am now testing it on Excel 365 in the other. The macro starts by creating a blank workbook. It errored out when trying to append rows to the macro created spreadsheet. Upon analysis, I noticed Excel on the 2nd PC creating a blank workbook in compatibility mode. Why? Isn't that only when it sees something that isn't compatible with the current version?

I did a full online repair to my Office 365 hoping that would resolve the issue but it does not. I'm at a loss as what to do.

Thanks.

Found the issue! The Excel Options section under SAVE was set to a default of setting all workbooks to xls format.
