I successfully parsed an xls file using Spreadsheet::ParseExcel::SaveParser and modified it with Spreadsheet::WriteExcel.

However working with xlsx file is a whole different thing. I am trying to figure out how to work with Spreadsheet::XLSX for parsing and how to make it work with Excel::Writer::XLSX. Spreadsheet::ParseExcel::SaveParser has a SaveAs() method that makes it possible to apply Spreadsheet::WriteExcel methods on the parsed xml file, but I don't understand how to make it work with xlsx file

When using Spreadsheet::ParseExcel::SaveParser and Spreadsheet::WriteExcel I can write:

#!/usr/bin/perl -w

use strict;
use Spreadsheet::ParseExcel;
use Spreadsheet::ParseExcel::SaveParser;

# Open the template with SaveParser
my $parser   = new Spreadsheet::ParseExcel::SaveParser;
my $template = $parser->Parse('template.xls');

# Rewrite the file or save as a new file
$workbook = $template->SaveAs('new.xls');

# Use Spreadsheet::WriteExcel methods
my $worksheet  = $workbook->sheets(0);
$worksheet->write($row+2, $col, "World2");

$workbook->close();

I would like to do the same with xlsx files. therefore I'm trying to use Spreadsheet::XLSX and Excel::Writer::XLSX. Instead of:

my $parser   = new Spreadsheet::ParseExcel::SaveParser;
my $template = $parser->Parse('template.xls');
[download]

I use

my $excel = Spreadsheet::XLSX -> new ('test.xlsx');
[download]

Now, after parsing the xlsx file I would like to add some data to it and I don't know how to do it. As you can see above when using Spreadsheet::ParseExcel::SaveParser I used SaveAs() function, but Spreadsheet::XLSX dosn't have a SaveAs() method. So how do I add data to parsed xlsx file?

I could not find an answer to my question in this link: http://search.cpan.org/~dmow/Spreadsheet-XLSX-0.13-withoutworldwriteables/lib/Spreadsheet/XLSX.pm Thanks you for your help :)
