Something like:
Code:
#! /usr/bin/perl

use strict;
use warnings;
use Spreadsheet::WriteExcel;

my $file = shift @ARGV;
my $workbook = Spreadsheet::WriteExcel->new($file) or die "can't create worksheet: $!";

my $dest = shift @ARGV;
chdir $dest or die "no such directory: $!";
opendir my $dh, '.' or die "can't open directory: $!";
my @files = sort grep { m{^[^.]} } readdir($dh);
close $dh; 

foreach my $file (@files) {
    open my $in, '<', $file or die "Could not open file: $!";

    $file =~ s{\..*$}{};
    my $worksheet   = $workbook->add_worksheet($file);

    my @prevRow = ();
    my $row = 0;

    while(<$in>) {
        my @currRow  = split(',', $_);
        my $col = 0;

        while ($col < @currRow) {
            last if @prevRow < $col || $currRow[$col] ne $prevRow[$col];
            $worksheet->write($row, $col, '');
            $col++;
        }

        while ($col < @currRow) {
            $worksheet->write($row, $col, $currRow[$col]);
            $col++;
        }

        @prevRow = @currRow;
        $row++;
    }
}

Invoked with:
Code:
scriptname workbookfile sourcedir...

Some notes:
  • if ( -d $dest ) { was not needed, the previous chdir would have failed if $dest was not a directory.
  • chomp $file is not needed, a trailing newline is an acceptable (if not appreciated) character in a directory entry
  • Be reluctant to use system calls in a perlscript. In this case, my $sheetname = `basename $file | cut -d. -f1`; was replaced by $file =~ s{\..*$}{}; as $file is already a "basename" and you were just trimming off everything after the first ".".
