=head1 NAME

Spreadsheet::ParseExcel::Workbook - A class for Workbooks.

=head1 SYNOPSIS

See the documentation for Spreadsheet::ParseExcel.

=head1 DESCRIPTION

This module is used in conjunction with Spreadsheet::ParseExcel. See the documentation for L<Spreadsheet::ParseExcel>.


=head1 Methods

The following Workbook methods are available:

    $workbook->worksheets()
    $workbook->worksheet()
    $workbook->worksheet_count()
    $workbook->get_filename()
    $workbook->get_print_areas()
    $workbook->get_print_titles()
    $workbook->using_1904_date()


=head2 worksheets()

The C<worksheets()> method returns an array of Worksheet objects. This was most commonly used to iterate over the worksheets in a workbook:

    for my $worksheet ( $workbook->worksheets() ) {
        ...
    }


=head2 worksheet()

The C<worksheet()> method returns a single C<Worksheet> object using either its name or index:

    $worksheet = $workbook->worksheet('Sheet1');
    $worksheet = $workbook->worksheet(0);

Returns C<undef> if the sheet name or index doesn't exist.


=head2 worksheet_count()

The C<worksheet_count()> method returns the number of Woksheet objects in the Workbook.

    my $worksheet_count = $workbook->worksheet_count();


=head2 get_filename()

The C<get_filename()> method returns the name of the Excel file of C<undef> if the data was read from a filehandle rather than a file.

    my $filename = $workbook->get_filename();


=head2 get_print_areas()

The C<get_print_areas()> method returns an array ref of print areas.

    my $print_areas = $workbook->get_print_areas();

Each print area is as follows:

    [ $start_row, $start_col, $end_row, $end_col ]

Returns undef if there are no print areas.


=head2 get_print_titles()

The C<get_print_titles()> method returns an array ref of print title hash refs.

    my $print_titles = $workbook->get_print_titles();

Each print title array ref is as follows:

    {
        Row    => [ $start_row, $end_row ],
        Column => [ $start_col, $end_col ],
    }


Returns undef if there are no print titles.


=head2 using_1904_date()

The C<using_1904_date()> method returns true if the Excel file is using the 1904 date epoch instead of the 1900 epoch.

    my $using_1904_date = $workbook->using_1904_date();

 The Windows version of Excel generally uses the 1900 epoch while the Mac version of Excel generally uses the 1904 epoch.

Returns 0 if the 1900 epoch is in use.
