Hello gauss76,

You can also try Spreadsheet::Read, there is also a nice short tutorial about it How to read an Excel file in Perl.

But to be honest most likely the error that you are getting will tell you what is wrong with your file. Try to create a new xlsx file e.g. test.xlsx insert one or two lines of data and try to open it with your script. If this works then your other file is corrupted and it can not be processed (most likely).

Hope this helps, let us know if your problem get's resolved. BR / Thanos
