Scrolling probability chart and excell questions

When I convert Excel sheets to VBulletin tables, I save them as tab-delimited text files.

Then you can do this in any decent text editor:
[noparse]
- global find and replace [tab] with |
- add

to the top
- add

to the bottom
[/noparse]

But I usually just run this Perl script.

 Spoiler

Code:

#!usr/bin/perl
#Converts a tab-delimited text file to a BBcode table.

use warnings;
use strict;

my @params;
my $file;

die "Usage: perl $0 [input] >[output]" unless (@ARGV);
foreach (@ARGV) #find files matching parameters
{
    chomp;
    if (/^-(\w+)/) { push(@params, $1); }
    else { $file = $_; last; }
}

print "[table";
print ("=".join(";", @params)) if (@params);
print "]";

open(FILE, $file);
while (<FILE>)
{
    chomp;
    next unless /\w/;
    s/\t/|/g;
    print $_;
}
print "[/TABLE]";

Perl looks weird @_@

And yeah, the tab delimited is what I meant. I just remember once opening some sort of Excel file in a text editor and finding meaningful-looking stuff in it, when I didn't have Excel or OpenOffice on said computer.
