Bonsoir, I see Spreadsheet-TieExcel is not available at this time for Perl V10. I guess installing Spreadsheet-TieExcel for Perl V8 will not work with V10. Should I install a Perl V8 version besides the actual Perl V10, and run what I want in Perl V8 - forgetting V10 for a while ? Sorry for the ignorance. Merci beaucoup. fr6drv
