Hi Monks, Is it possible via 'perl' to disable users from cut, copy & pasting data. I have created a xlsx worksheet with the use of the Excel::Writer::XLSX; module, but even though numerous columns have format vailadations set, it is still possible to copy data into those cells. this is just a short sample of my script below.

#!/usr/bin/perl -w
use strict;
use Spreadsheet::WriteExcel;
use Excel::Writer::XLSX;
my $workbook   = Excel::Writer::XLSX->new("C:\\Temp\\test.xlsx");
my $worksheet1 = $workbook->add_worksheet();
$worksheet1->freeze_panes( 1, 0 );
my $unlocked = $workbook->add_format( locked => 0 );

my $header  = $workbook->add_format( locked => 1 );
my $header2 = $workbook->add_format( locked => 1 );
$header->set_color('white');
$header->set_align('left');
$header->set_pattern();
$header->set_bg_color('orange');

$worksheet1->protect();

for my $i ( 0 .. 60 ) {
    $worksheet1->write( 0, $i, 'header', $header, );
}
my @score_attain = (
    'P1', 'P2',  'P3', 'P4',  'P5', 'P6',  'P7', 'P8',  '1W', '1W+',
    '1B', '1B+', '1S', '1S+', '2W', '2W+', '2B', '2B+', '2S', '2S+',
    '3W', '3W+', '3B', '3B+', '3S', '3S+', '4W', '4W+', '4B', '4B+',
    '4S', '4S+', '5W', '5W+', '5B', '5B+', '5S', '5S+',
);
for my $i ( 1 .. 1000 ) {

    $worksheet1->data_validation(
        $i, 6,

        {
            validate      => 'list',
            source        => [@score_attain],
            input_title   => 'Select an option',
            input_message => 'Select a value from the drop down list',
            error_title   => 'Input value is not valid!',
            error_message => 'Select a value from the drop down list',
        }
    );
}

for my $i ( 1 .. 100 ) {
    for my $j ( 0 .. 60 ) {
        $worksheet1->set_row( $i, undef, $unlocked );
        $worksheet1->{CutCopyMode} = 0;

    }
}
