The first bit of help is to see Markup in the Monastery and use <code> tags so the code is readable. Like:

#!/usr/bin/perl
use strict;
use warnings;
use Text::CSV;

my $file = '112008.csv';
my $output='112008.txt';

my $csv = Text::CSV->new();

open (CSV, "<", $file) or die $!;
open(OUTFILE,">$output") || die "Can't open file $output";


while (<CSV>) {
    if ($csv->parse($_)) {
        my @columns = $csv->fields();
        printf OUTFILE "@columns\n";
    } else {
        my $err = $csv->error_input;
        print "Failed to parse line: $err";
    }
}

close CSV;

Lot easier to read and comment on then.
