.IX Title "Spreadsheet::ParseExcel::SaveParser 3"
.TH Spreadsheet::ParseExcel::SaveParser 3 "2011-04-06" "perl v5.8.8" "User Contributed Perl Documentation"
.SH "NAME"
Spreadsheet::ParseExcel::SaveParser \- Rewrite an existing Excel file.
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
Say we start with an Excel file that looks like this:
.PP
.Vb 8
\& -----------------------------------------------------
\& | | A | B | C |
\& -----------------------------------------------------
\& | 1 | Hello | ... | ... | ...
\& | 2 | World | ... | ... | ...
\& | 3 | *Bold text* | ... | ... | ...
\& | 4 | ... | ... | ... | ...
\& | 5 | ... | ... | ... | ...
.Ve
.PP
Then we process it with the following program:
.PP
.Vb 1
\& #!/usr/bin/perl
.Ve
.PP
.Vb 2
\& use strict;
\& use warnings;
.Ve
.PP
.Vb 2
\& use Spreadsheet::ParseExcel;
\& use Spreadsheet::ParseExcel::SaveParser;
.Ve
.PP
.Vb 3
\& # Open an existing file with SaveParser
\& my $parser = Spreadsheet::ParseExcel::SaveParser->new();
\& my $template = $parser->Parse('template.xls');
.Ve
.PP
.Vb 4
\& # Get the first worksheet.
\& my $worksheet = $template->worksheet(0);
\& my $row = 0;
\& my $col = 0;
.Ve
.PP
.Vb 2
\& # Overwrite the string in cell A1
\& $worksheet->AddCell( $row, $col, 'New string' );
.Ve
.PP
.Vb 2
\& # Add a new string in cell B1
\& $worksheet->AddCell( $row, $col + 1, 'Newer' );
.Ve
.PP
.Vb 3
\& # 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};
.Ve
.PP
.Vb 1
\& $worksheet->AddCell( $row, $col + 2, 'Newest', $format_number );
.Ve
.PP
.Vb 2
\& # Write over the existing file or write a new file.
\& $template->SaveAs('newfile.xls');
.Ve
.PP
We should now have an Excel file that looks like this:
.PP
.Vb 8
\& -----------------------------------------------------
\& | | A | B | C |
\& -----------------------------------------------------
\& | 1 | New string | Newer | *Newest* | ...
\& | 2 | World | ... | ... | ...
\& | 3 | *Bold text* | ... | ... | ...
\& | 4 | ... | ... | ... | ...
\& | 5 | ... | ... | ... | ...

.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \f(CW\*(C`Spreadsheet::ParseExcel::SaveParser\*(C'\fR module rewrite an existing Excel file by reading it with \f(CW\*(C`Spreadsheet::ParseExcel\*(C'\fR and rewriting it with \f(CW\*(C`Spreadsheet::WriteExcel\*(C'\fR.
.SH "METHODS"
.IX Header "METHODS"
.SH "Parser"
.IX Header "Parser"
.Sh "\fInew()\fP"
.IX Subsection "new()"
.Vb 1
\& $parse = new Spreadsheet::ParseExcel::SaveParser();
.Ve
.PP
Constructor.
.Sh "\fIParse()\fP"
.IX Subsection "Parse()"
.Vb 1
\& $workbook = $parse->Parse($sFileName);
.Ve
.PP
.Vb 1
\& $workbook = $parse->Parse($sFileName , $formatter);
.Ve
.PP
Returns a \*(L"Workbook\*(R" object. If an error occurs, returns undef.
.PP
The optional \f(CW$formatter\fR is a Formatter Class to format the value of cells.
.SH "Workbook"
.IX Header "Workbook"
The \f(CW\*(C`Parse()\*(C'\fR method returns a \f(CW\*(C`Spreadsheet::ParseExcel::SaveParser::Workbook\*(C'\fR object.
.PP
This is a subclass of the Spreadsheet::ParseExcel::Workbook and has the following methods:
.Sh "\fIworksheets()\fP"
.IX Subsection "worksheets()"
Returns an array of \*(L"Worksheet\*(R" objects. This was most commonly used to iterate over the worksheets in a workbook:
.PP
.Vb 3
\& for my $worksheet ( $workbook->worksheets() ) {
\& ...
\& }
.Ve
.Sh "\fIworksheet()\fP"
.IX Subsection "worksheet()"
The \f(CW\*(C`worksheet()\*(C'\fR method returns a single \f(CW\*(C`Worksheet\*(C'\fR object using either its name or index:
.PP
.Vb 2
\& $worksheet = $workbook->worksheet('Sheet1');
\& $worksheet = $workbook->worksheet(0);
.Ve
.PP
Returns \f(CW\*(C`undef\*(C'\fR if the sheet name or index doesn't exist.
.Sh "\fIAddWorksheet()\fP"
.IX Subsection "AddWorksheet()"
.Vb 1
\& $workbook = $workbook->AddWorksheet($name, %properties);
.Ve
.PP
Create a new Worksheet object of type \f(CW\*(C`Spreadsheet::ParseExcel::Worksheet\*(C'\fR.
.PP
The \f(CW%properties\fR hash contains the properties of new Worksheet.
.Sh "AddFont"
.IX Subsection "AddFont"
.Vb 1
\& $workbook = $workbook->AddFont(%properties);
.Ve
.PP
Create new Font object of type \f(CW\*(C`Spreadsheet::ParseExcel::Font\*(C'\fR.
.PP
The \f(CW%properties\fR hash contains the properties of new Font.
.Sh "AddFormat"
.IX Subsection "AddFormat"
.Vb 1
\& $workbook = $workbook->AddFormat(%properties);
.Ve
.PP
The \f(CW%properties\fR hash contains the properties of new Font.
.SH "Worksheet"
.IX Header "Worksheet"
Spreadsheet::ParseExcel::SaveParser::Worksheet
.PP
Worksheet is a subclass of Spreadsheet::ParseExcel::Worksheet.
And has these methods :
.PP
The \f(CW\*(C`Worksbook::worksheet()\*(C'\fR method returns a \f(CW\*(C`Spreadsheet::ParseExcel::SaveParser::Worksheet\*(C'\fR object.
.PP
This is a subclass of the Spreadsheet::ParseExcel::Worksheet and has the following methods:
.SH "AddCell"
.IX Header "AddCell"
.Vb 1
\& $workbook = $worksheet->AddCell($row, $col, $value, $format [$encoding]);
.Ve
.PP
Create new Cell object of type \f(CW\*(C`Spreadsheet::ParseExcel::Cell\*(C'\fR.
.PP
The \f(CW$format\fR parameter is the format number rather than a full format object.
.PP
To specify just same as another cell,
you can set it like below:
.PP
.Vb 5
\& $row = 0;
\& $col = 0;
\& $worksheet = $template->worksheet(0);
\& $cell = $worksheet->get_cell( $row, $col );
\& $format_number = $cell->{FormatNo};
.Ve
.PP
.Vb 1
\& $worksheet->AddCell($row +1, $coll, 'New data', $format_number);
.Ve
.SH "TODO"
.IX Header "TODO"
Please note that this module is currently (versions 0.50\-0.60) undergoing a major
restructuring and rewriting.
.SH "Known Problems"
.IX Header "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.
.PP
Only last print area will remain. (Others will be removed)
