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)
