NAME
Spreadsheet::ParseExcel::SaveParser - Rewrite an existing Excel file.
SYNOPSIS
Say we start with an Excel file that looks like this:
-----------------------------------------------------
| | A | B | C |
-----------------------------------------------------
| 1 | Hello | ... | ... | ...
| 2 | World | ... | ... | ...
| 3 | *Bold text* | ... | ... | ...
| 4 | ... | ... | ... | ...
| 5 | ... | ... | ... | ...
Then we process it with the following program:
#!/usr/bin/perl
use strict;
use warnings;
use Spreadsheet::ParseExcel;
use Spreadsheet::ParseExcel::SaveParser;
# Open an existing file with SaveParser
my $parser = Spreadsheet::ParseExcel::SaveParser->new();
my $template = $parser->Parse('template.xls');
# Get the first worksheet.
my $worksheet = $template->worksheet(0);
my $row = 0;
my $col = 0;
# Overwrite the string in cell A1
$worksheet->AddCell( $row, $col, 'New string' );
# Add a new string in cell B1
$worksheet->AddCell( $row, $col + 1, 'Newer' );
# Add a new string in cell C1 with the format from cell A3.
my $cell = $worksheet->get_cell( $row + 2, $col );
my $format_number = $cell->{FormatNo};
$worksheet->AddCell( $row, $col + 2, 'Newest', $format_number );
# Write over the existing file or write a new file.
$template->SaveAs('newfile.xls');
We should now have an Excel file that looks like this:
-----------------------------------------------------
| | A | B | C |
-----------------------------------------------------
| 1 | New string | Newer | *Newest* | ...
| 2 | World | ... | ... | ...
| 3 | *Bold text* | ... | ... | ...
| 4 | ... | ... | ... | ...
| 5 | ... | ... | ... | ...
DESCRIPTION
The "Spreadsheet::ParseExcel::SaveParser" module rewrite an existing Excel file by reading
it with "Spreadsheet::ParseExcel" and rewriting it with "Spreadsheet::WriteExcel".
METHODS
Parser
new()
$parse = new Spreadsheet::ParseExcel::SaveParser();
Constructor.
Parse()
$workbook = $parse->Parse($sFileName);
$workbook = $parse->Parse($sFileName , $formatter);
Returns a "Workbook" object. If an error occurs, returns undef.
The optional $formatter is a Formatter Class to format the value of cells.
Workbook
The "Parse()" method returns a "Spreadsheet::ParseExcel::SaveParser::Workbook" object.
This is a subclass of the Spreadsheet::ParseExcel::Workbook and has the following methods:
worksheets()
Returns an array of "Worksheet" objects. This was most commonly used to iterate over the
worksheets in a workbook:
for my $worksheet ( $workbook->worksheets() ) {
...
}
worksheet()
The "worksheet()" method returns a single "Worksheet" object using either its name or
index:
$worksheet = $workbook->worksheet('Sheet1');
$worksheet = $workbook->worksheet(0);
Returns "undef" if the sheet name or index doesn't exist.
AddWorksheet()
$workbook = $workbook->AddWorksheet($name, %properties);
Create a new Worksheet object of type "Spreadsheet::ParseExcel::Worksheet".
The %properties hash contains the properties of new Worksheet.
AddFont
$workbook = $workbook->AddFont(%properties);
Create new Font object of type "Spreadsheet::ParseExcel::Font".
The %properties hash contains the properties of new Font.
AddFormat
$workbook = $workbook->AddFormat(%properties);
The %properties hash contains the properties of new Font.
Worksheet
Spreadsheet::ParseExcel::SaveParser::Worksheet
Worksheet is a subclass of Spreadsheet::ParseExcel::Worksheet. And has these methods :
The "Worksbook::worksheet()" method returns a
"Spreadsheet::ParseExcel::SaveParser::Worksheet" object.
This is a subclass of the Spreadsheet::ParseExcel::Worksheet and has the following
methods:
AddCell
$workbook = $worksheet->AddCell($row, $col, $value, $format [$encoding]);
Create new Cell object of type "Spreadsheet::ParseExcel::Cell".
The $format parameter is the format number rather than a full format object.
To specify just same as another cell, you can set it like below:
$row = 0;
$col = 0;
$worksheet = $template->worksheet(0);
$cell = $worksheet->get_cell( $row, $col );
$format_number = $cell->{FormatNo};
$worksheet->AddCell($row +1, $coll, 'New data', $format_number);
TODO
Please note that this module is currently (versions 0.50-0.60) undergoing a major
restructuring and rewriting.
Known Problems
You can only rewrite the features that Spreadsheet::WriteExcel supports so macros, graphs
and some other features in the original Excel file will be lost. Also, formulas aren't
rewritten, only the result of a formula is written.
Only last print area will remain. (Others will be removed)
