Here is a simple Tk example. I've just put the row-col numbers in the cells, but you could load $cells{$row}{$col}{'data'} with your spreadsheet output and use that for the text. It is also possible to change fonts, cell colors, text color, etc. When you click the png-output button, be patient, it may take a second or 2.

#!/usr/bin/perl
use warnings;
use strict;
use Tk;
use Tk::WinPhoto;
use Tk::PNG;

my $mw = tkinit;
my $width = 500;
my $height = 700;

my $canv = $mw->Canvas(width => $width, height =>$height)->pack();

#set cell size adjustment 
my $x = 50;
my $y = 20;

my $rows = int( $height / $y + 1 ) - 1; #make it 0 based 
my $cols = int( $width / $x + 1 ) - 1;
print "rows->$rows  cols->$cols\n";
               
my %cells;
foreach my $row ( 0 .. $rows ) {
    foreach my $col ( 0 .. $cols ) {

    $cells{$row}{$col}{'rect'} = $canv->createRectangle(
      $col * $x, $row * $y, $col * $x + $x, $row * $y + $y,
               #-width   => 1, 
               -outline => 'white',
           );

    $cells{$row}{$col}{'text'} = $canv->createText(
         $col * $x + $x/2  , $row * $y + $y/2,
         -text  => "$row - $col",
         -anchor => 'center',
         -fill => 'black',
           );
                             
    }
}


my $canvbutton = $mw->Button(-text=>'Canvas Capture',
                             -command => \&canv_capture,
                            )->pack;
                        
MainLoop;
##########################################################  
sub canv_capture{

my $image = $mw->Photo(-format => 'Window',
                        -data => oct($canv->id)
                       );

my $pathname = './canvas.'.time.'.png';
$image->write($pathname, -format => 'PNG');

}

• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
