DESCRIPTION

"Spreadsheet::Wright" is a fork of Spreadsheet::Write and may be used as a drop-in replacement.

"Spreadsheet::Wright" writes files in CSV, Microsoft Excel, HTML and OpenDocument formats. It is especially suitable for building various dumps and reports where rows are built in sequence, one after another.

It is not especially suitable for modifying existing files.

The name is a not just pun on ``write'' - the word ``wright'' means worker or crafter, and "Spreadsheet::Wright" does a lot of the work of spreadsheet output for you!

Constructor

"Spreadsheet::Wright->new(%args)"
  $spreadsheet = Spreadsheet::Wright->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 (mandatory)
  • encoding - encoding of output file (optional, csv format only)
  • format - format of spreadsheet - 'csv', 'xls', 'html', 'xhtml', 'xml', 'ods', 'json' or 'auto' (default).
  • sheet - first sheet name (optional, not supported by some formats)
  • styles - defines cell formatting shortcuts (optional)
  • failsafe - boolean - if true, falls back to CSV in emergencies

If file format is 'auto' (or omitted), the format is guessed from the filename extension, defaulting to 'csv'.

Methods

"addrow($cell_1, $cell_2, ...)"
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 cell
    style           formatting style, as defined in new()
    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
    align           alignment
    valign          vertical alignment
    width           column width, excel units (only makes sense once per column)
    header          boolean; is this cell a header?

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::Wright->new(
    file      => 'employees.xls',
    styles    => {
      important => { font_weight => 'bold' },
      },
    );
  $sp->addrow(
    { content => 'First Name', font_weight => 'bold' },
    { content => 'Last Name',  font_weight => 'bold' },
    { content => 'Age',        style => 'important' },
    );
  $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   => 'important',
    content => ['First Name', 'Last Name', 'Age'],
    });

Not all styling options are supported in all formats.

"addrows(\@row_1, \@row_2, ...)"
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(). Only implemented for Excel spreadsheets so far.
"close"
Saves the spreadsheet to disk (some of the modules save incrementally anyway) and closes the file. Calling this explicitly is usually un-necessary, as the Perl garbage collector will do the job eventually anyway. Once a spreadsheet is closed, calls to addrow() will fail.
"error"
Returns the latest recoverable error.
