I have an excel file which I need to extract data from. When I open it (with Spreadsheet::XLSX) it reports an empty file - no worksheets. This is not correct. Opening it with Excel itself shows that there is data.

The problem might be that the file wasn't created by Excel itself - it may have been created by another program, which pretends to create 100% compatible Excel files.

Is there any way to convert such files to valid Excel files, or is there another Perl module that can open and process them? I need a permanent solution, to process many such files automatically.

The file can be found here: https://ufile.io/f06gn

Thank you very much!
