Hi. Thanks to you all I have gotten a lot further. I changed the use statement to
use Spreadsheet::XLSX::Utility2007;
The xls2csv line is now just:
my $sCsvTxt = xls2csv($sFileName, $sRegion, $iRotate);
It doesn't error there anymore, so I guess that means it is exporting the xls2csv function, but now I get this error: "Tk::Error: Can't locate object method "new" via package "Spreadsheet::XLSX" at C
:/strawberry/perl/site/lib/Spreadsheet/XLSX/Utility2007.pm line 952."
I guess that means something is wrong with either Spreadsheet/XLSX.pm or Spreadsheet/XLSX/Utility2007.pm or am I missing something or is my installation corrupt?
***Update***
I used my Vanilla Perl installation instead of my Strawberry one by changing the Path in Windows. I then reinstalled Spreadsheet::XLSX and I'm still getting the same error. Is new perhaps a function being erroneously called as a method?
