The RATS Software Forum

Does anybody else have trouble reading from xlsx-files with RATS 8.1?

When loading an xlsx-file and specifying "format=xlsx" I get the following error message

Code: Select all

Not XLSX workbook


Do I have to take something special into account when saving the Excel file?

I figured out that it is a problem of the Excel file rather than with RATS. But since I have a plain xlsx-file with only two sheets (see attachement) I am puzzled about what the problem is.
