parseExcel does not work on google sheets file

[lilkeet]

Creating an excel file on google sheets, downloading it as an xlsx file, and running parseExcel does not work. The linked file does read the sheet name, but none of the actual data is read properly. No error is thrown. echo'ing the sheet shows that it reads it as two plusses (+'s) and a space.

This is on nim v1.6.10, ubuntu.
