Re^2: serial number generator

[royserna03]

Thank You so much! that was a really big help, I really appreciate the help! I just have a few more questions if that's ok. How can I store the last number create, so that after the usr closes the program it picks it right back from where it ended. Ex. last number is ITS0012, usr closes and opens again and the first number that the usr gets is ITS0013. Also how can I have two spread sheets, one with the recently made numbers and another one with all the numbers that have been created? Again I want to thank you for such a fast and awesome response! I was so stuck, I really appreciate the support!

I think this will do what you want:

#!/usr/bin/perl
use strict;
use warnings;
use Excel::Writer::XLSX;
use Spreadsheet::XLSX;

my $master       = 'master.xlsx';
-f $master
    or die "Spreadsheet '$master' not found: $!";
my $excel        =  Spreadsheet::XLSX->new($master)
    or die "Cannot open spreadsheet '$master' for reading: $!";
my $sheet        =  $excel->{Worksheet}[0];
my $last_old_id  =  $sheet->{Cells}[ $sheet->{MaxRow} ][0]{Val} // 'IT
+S0000';
   $last_old_id  =~ /(\d+)/;
my $first_new_id =  $1 + 1;

print "How many Serial Numbers do you need?\n";
my $mal  = <STDIN>;
my $comp = 'ITS';
my @array;

for my $number (1 .. ($first_new_id + $mal - 1))
{
    my $exp = $comp . sprintf("%04d", $number);
    push @array, $exp;
}

my $simple       = 'simple.xlsx';
my $workbook     =  Excel::Writer::XLSX->new($simple)
    or die "Cannot open spreadsheet '$simple' for writing: $!";
my $worksheet    =  $workbook->add_worksheet();
my @array2       =  @array[($first_new_id - 1) .. ($first_new_id + $ma
+l - 2)];

$worksheet->write_col(0, 0, \@array2);

$workbook        =  Excel::Writer::XLSX->new($master)
    or die "Cannot open spreadsheet '$master' for writing: $!";
$worksheet       =  $workbook->add_worksheet();

$worksheet->write_col(0, 0, \@array);

The full set of IDs is stored in the first column of master.xlsx. The new IDs are (over-)written into the file simple.xlsx, as before.

Hope that helps,

Update: As Anonymous Monk implies below, you have to create an Excel file called master.xlsx first (using Excel), before you run the code. The file should initially be empty.

This code is so great! Thank You! I just get an error when I try to run it. It says "Spreadsheet 'master.xlsx' not found: no such file or directory at idperl.pl line 8. I tried looking for an error but I could not find anything. Do you know why it is doing this? Again Thank You so much! you have helped a lot!

How do you know?

It says "Spreadsheet 'master.xlsx' not found: no such file or directory at

Do you have a file master.xlsx?
