Can anyone explain/solve this problem?

. qlqc30, filename("mira_feb_2020_kun_baseline.dta") version(3) grp(1)
(ComparisonOfTransana_DATA_NOHDRS_2020-02-27_1318.csv)
_xlshwritestrcol(): 9901 Stata returned error
export_excel_write_file(): - function returned error
export_excel_export_file(): - function returned error
<istmt>: - function returned error
r(9901);

end of do-file

r(9901);

Thanks,
Therese
