I need to read a directory for all tab-delimited files (they will have a .csv extension) and insert a new column that contains the file name(without the path) and write the modified file back to the original file name. I've tried using ParseExcel/WriteExel , CTable, AnyData, and Text::xSV and usually get stuck on creating and merging the new column or rewrtiing a corrupted file (for excel). Here's one non-working version.....

#!/usr/bin/perl -w

my $dir = 'C:/Programs' ;
use strict;
use Data::CTable;

#Read Directory for all '.csv' file

opendir(TD, $dir) || die "Can not open directory: $!:";
my @FILES=grep(/\.csv/i, readdir TD);
print @FILES;
closedir(TD);

my $file = $FILES[0];
my $Full = $file;
my $People = Data::CTable->new("roy.csv" ) || die "Can not open file: 
+$!:";
$People->clean_ws();
$People->col(PCSFileName => "hello");



$People->write(_FileName => "Roy_results.csv", _LineEnding => "dos");
foreach my $file (@FILES) {
     my $t = Data::Table::fromCSV($file) || die "Can not open file: $!
+:";
     $t->addCol($file, "PCS Filename") || die "Can not add Column ";
     print $t->csv || die "Can not write output";
}

Here's another.......

#!/usr/bin/perl -w

my $dir = 'C:/Programs' ;
use strict;
use Data::Table;

#Read Directory for all '.csv' file

opendir(TD, $dir) || die "Can not open directory: $!:";
my @FILES=grep(/\.csv/i, readdir TD);
print @FILES;
closedir(TD);

my $file = $FILES[0];
my $t = Data::Table::fromTSV($file,1) || die "Can not open file: $!:";
print $t->tsv
foreach my $file (@FILES) {
     my $t = Data::Table::fromCSV($file) || die "Can not open file: $!
+:";
     $t->addCol($file, "PCS Filename") || die "Can not add Column ";
     print $t->csv || die "Can not write output";
}
