DESCRIPTION
    "Spreadsheet::Write" writes files in CSV, XLS (Microsoft Excel 97), and
    potentially other formats. It is especially suitable for building
    various dumps and reports where rows are built in sequence, one after
    another.

METHODS
  new ()
        $spreadsheet = Spreadsheet::Write->new(
            file            => 'table.xls',
            styles          => {
                mynumber        => '#,##0.00',
            }
        );

    Creates a new spreadsheet object. It takes a list of options. The
    following are valid:

        file        filename of the new spreadsheet or an IO handle (mandatory)
        encoding    encoding of output file (optional, csv format only)
        format      format of spreadsheet - 'csv', 'xls', or 'auto' (default)
        sheet       Sheet name (optional, not supported by some formats)
        styles      Defines cell formatting shortcuts (optional)

    If file format is 'auto' (or omitted), the format is guessed from the
    filename extention. If impossible to guess the format defaults to 'csv'.

    An IO-like handle can be given as 'file' argument (IO::File, IO::Scalar,
    etc). In this case the format argument is mandatory.

    Default styles are: header => { font_weight => 'bold', type => 'string',
    }, ntext => { format => '@', type => 'string', }, money => { format =>
    '$#,##0.00;-$#,##0.00', },

  addrow(arg1,arg2,...)
    Adds a row into the spreadsheet. Takes arbitrary number of arguments.
    Arguments represent cell values and may be strings or hash references.
    If an argument is a hash reference, it takes the following structure:

        content         value to put into the cell
        style           formatting style, as defined in new(), scalar or array-ref
        type            type of the content (defaults to 'auto')
        format          number format (see Spreadsheet::WriteExcel for details)
        font_weight     weight of font. Only valid value is 'bold'
        font_style      style of font. Only valid value is 'italic'
        font_decoration 'underline' or 'strikeout' (or both, space separated)
        font_face       font of column; default is 'Arial'
        font_color      color of font (see Spreadsheet::WriteExcel for color values)
        font_size       size of font
        bg_color        color of background (see Spreadsheet::WriteExcel for color values)
        align           alignment
        valign          vertical alignment
        width           column width, excel units (only makes sense once per column)
        height          row height, excel units (only makes sense once per row)
        comment         hidden comment for the cell, where supported

    Styles can be used to assign default values for any of these formatting
    parameters thus allowing easy global changes. Other parameters specified
    override style definitions.

    Example:

        my $sp=Spreadsheet::Write->new(
            file        => 'employees.xls',
            styles      => {
                header => { font_weight => 'bold' },
            },
        );
        $sp->addrow(
            { content => 'First Name', font_weight => 'bold' },
            { content => 'Last Name', font_weight => 'bold' },
            { content => 'Age', style => 'header' },
        );
        $sp->addrow("John","Doe",34);
        $sp->addrow("Susan","Smith",28);

    Note that in this example all header cells will have identical
    formatting even though some use direct formats and one uses style.

    If you want to store text that looks like a number you might want to use
    { type => 'string', format => '@' } arguments. By default the type
    detection is automatic, as done by for instance Spreadsheet::WriteExcel
    write() method.

    It is also possible to supply an array reference in the 'content'
    parameter of the extended format. It means to use the same formatting
    for as many cells as there are elements in this array. Useful for
    creating header rows. For instance, the above example can be rewritten
    as:

        $sp->addrow(
            { style => 'header',
              content => [ 'First Name','Last Name','Age' ],
            }
        );

    Not all styling options are supported in all formats. Where they are not
    supported they are safely ignored.

  addrows([$cell1A,$cell1B,...],[$cell2A,$cell2B,...],...)
    Shortcut for adding multiple rows.

    Each argument is an arrayref representing a row.

    Any argument that is not a reference (i.e. a scalar) is taken to be the
    title of a new worksheet.

  addsheet(name)
    Adds a new sheet into the document and makes it active. Subsequent
    addrow() calls will add rows to that new sheet.

    For CSV format this call is NOT ignored, but produces a fatal error
    currently.

  freeze($row, $col, $top_row, $left_col))
    Sets a freeze-pane at the given position, equivalent to
    Spreadsheet::WriteExcel->freeze_panes(). Ignored for CSV files.

  close ()
    Finalizes the spreadsheet and closes the file. It is a good idea to call
    this method explicitly instead of relying on perl's garbage collector
    because for many formats the file may be in an unusable state until this
    method is called.

    Once a spreadsheet is closed, calls to addrow() will fail.
