... Text::CSV .. Any help re including the removal of the double quotes characters ...

Why break files? Anyway, see Text::CSV and try stuff (options controlling quoting and what not)

ask for input and output

Programs that ask for stuff are annoying, programs that stop and complain if they don't get what they need are much a joy :D

see @ARGV or Getopt::Long

@ARGV or die Usage();
my( $infile, $outfile ) = @ARGV;
