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
edit:
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');
I use
my $excel = Spreadsheet::XLSX -> new ('test.xlsx');
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.
Thanks you for your help :)
The Spreadsheet::XLSX module is a Parser, i.e. it is not supposed to write files, only to read and understand them.
To write the file back to disk, I suggest you the Excellent (no pun intended :) ) Excel::Writer::XLSX by John McNamara.
http://search.cpan.org/~jmcnamara/Excel-Writer-XLSX/lib/Excel/Writer/XLSX.pm
Basically you can slurp (via Spreadsheet::XLSX) the XLSX file into a multilevel hash reference structured like this:
$xlsx_as_read->{worksheet_name}->{column}->{row}=value;
Modifying the example on the CPAN link you posted:
use Text::Iconv;
my $converter = Text::Iconv -> new ("utf-8", "windows-1251");
# Text::Iconv is not really required.
# This can be any object with the convert method. Or nothing.
use Spreadsheet::XLSX;
my $xlsx_as_read;
my $excel = Spreadsheet::XLSX -> new ('test.xlsx', $converter);
foreach my $sheet (@{$excel -> {Worksheet}}) {
printf("Sheet: %s\n", $sheet->{Name});
$sheet -> {MaxRow} ||= $sheet -> {MinRow};
foreach my $row ($sheet -> {MinRow} .. $sheet -> {MaxRow}) {
$sheet -> {MaxCol} ||= $sheet -> {MinCol};
foreach my $col ($sheet -> {MinCol} .. $sheet -> {MaxCol}) {
my $cell = $sheet -> {Cells} [$row] [$col];
if ($cell) {
$xlsx_as_read->{$sheet->{Name}}->{$col}->{$row}=$cell -> {Val};
}
}
}
}
and then pour it back to an Excel::Writer::XLSX workbook, which can be written to disk.
my $new_workbook = Excel::Writer::XLSX->new( 'output_file_name.xlsx' );
#populate cells with a loop similar to the one before,
#iterating on $xlsx_as_read
