I have a comma delimited file which upper management imports into an Excel file. I figured I'd show some initiative and write a script to create the Excel file for them.

I'd never used Spreadsheet::WriteExcel before, but it was a breeze. The spreadsheet is exactly the way management uses it. The only difference is the size of the file. The file created by my perl script is much larger than the file created by importing the comma delimited file. Here's the breakdown:

Following is the script I'm using to create the file. I'd like to hear any suggestions regarding reducing the size of the Excel file. Like I said, I've never played with the module before, so I may be missing some obvious efficiency issues. 

#!/usr/bin/perl -w
use strict;
use Spreadsheet::WriteExcel::Big;

open (IN, "temp.txt") || die "Cannot open temp.txt\n";

# set up Excel spreadsheet
my $workbook  = Spreadsheet::WriteExcel::Big->new("temp.xls");
my $worksheet = $workbook->addworksheet();

my $inLine;
my $row = 0;

while ($inLine = <IN>) {
        my ($date, $log, $protocol, $firstIP, $secondIP, $packets) =
                split(/,/, $inLine);

        # strip port number if it exists
        if ($firstIP =~ /([\d.]+)\((\d+)\)/) {
            my $ip1 = $1;
            my $port1 = $2;
        } else {
            my $ip1 = $firstIP;
            my $port1 = " ";
        }
        if ($secondIP =~ /([\d.]+)\((\d+)\)/) {
            my $ip2 = $1;
            my $port2 = $2;
        } else {
            my $ip2 = $secondIP;
            my $port2 = " ";
        }

        push my @XLSarray,
             ($date, $log, $protocol, $ip1, $port1, $ip2, $port2, $pac
+kets);

        # print information to Excel spreadsheet
        my $col = 0;
        foreach my $XLSelement (@XLSarray) {
            $worksheet->write($row, $col, $XLSelement);
            $col++;
        }
        $row++;
}

$workbook->close();

If things get any worse, I'll have to ask you to stop helping me.
