Please provide the Excel file to me.

I think the reason was, that excel file was exported by previouse version of Zeta. If I export excel file with a new version and modify it, then it is imported with no errors.
I fixed my issue this way.
But for testing porposes attaching problem excel file
ZetaTestFile.xlsx
