I have not tried the other modules but I'm willing to give it a try. For what it's worth, though, the xls2csv I have does use Spreadsheet::Read. I believe it was installed when Spreadsheet::Read was installed via CPAN. (It uses Text::CSV_XS instead of Text::CSV and \r\n instead of \n but I did try those already with no change in my output.)
