I have abandoned my silly script from before since I found there is an xls2csv function in the Spreadsheet::XLSX::Utility module. Thanks for putting up with the previous post.

Question: I'm trying to call the xls2csv function from this module but it is unexported. How does one do this properly? Right now I'm getting the error: "Tk::Error: Undefined subroutine &main::xls2csv called at name of my script.pl line 33."

I found what I thought was an answer on the Web so I tried defining the function as "Spreadsheet::XLSX::Utility::xls2csv" but that gave me basically the same error:"Tk::Error: Undefined subroutine &Spreadsheet::XLSX::Utility::xls2csv name of my script.pl line 33.

Thanks in advance. Short script is below. 

#!/usr/local/bin/perl

use Spreadsheet::XLSX::Utility2007;
use Tk;

my $mw = new MainWindow;

my $mbar = $mw -> Menu();
$mw -> configure(-menu => $mbar);

my $file = $mbar -> cascade(-label=>"File", -underline=>0, -tearoff =>
+ 0);

$file -> checkbutton(-label =>"Open", -underline => 0,
        -command => [\&menuopenClicked, "Open"]);
$file -> command(-label =>"Save", -underline => 0,
        -command => [\&menusavedClicked, "Save"]);
$file -> separator();
$file -> command(-label =>"Exit", -underline => 1,
        -command => sub { exit } );

MainLoop;

sub menuopenClicked {
my $typesopen = [ ['Excel 2007 files', '.xlsx'],
                    ['All files',   '*'],];
            my $mainfilepath = $mw->getOpenFile(-filetypes => $typesop
+en,
                              -defaultextension => '.xlsx');          

my $sFileName = $mainfilepath ;
my $sRegion = '1-A1:G:110' ;
my $iRotate = 1;
my $sCsvTxt = xls2csv($sFileName, $sRegion, $iRotate);

sub menusavedClicked {
  my $typesaved = [ ['Excel 2007 files', '.xlsx'],
                    ['All files',   '*'],];
            my $saved = $mw->getSaveFile(-filetypes => $typessaved,
                              -defaultextension => '.csv');
open($saved, "> $saved") || die "Can't create <$saved> for output!\n";
  print ($saved $sCsvTxt) if $saved;    
close $saved;
}}
