Spreadsheet::ParseXLSX - parse XLSX files


version 0.14


  use Spreadsheet::ParseXLSX;

  my $parser = Spreadsheet::ParseXLSX->new;
  my $workbook = $parser->parse("file.xlsx");
  # see Spreadsheet::ParseExcel for further documentation


This module is an adaptor for Spreadsheet::ParseExcel that reads XLSX files.



Returns a new parser instance. Takes no parameters.


Parses an XLSX file. Parsing errors throw an exception. $file can be either a filename or an open filehandle. Returns a Spreadsheet::ParseExcel::Workbook instance containing the parsed data.


This module returns data using classes from Spreadsheet::ParseExcel, so for the most part, it should just be a drop-in replacement. That said, there are a couple areas where the data returned is intentionally different:


In Spreadsheet::ParseExcel, colors are represented by integers which index into the color table, and you have to use Spreadsheet::ParseExcel->ColorIdxToRGB in order to get the actual value out. In Spreadsheet::ParseXLSX, while the color table still exists, cells are also allowed to specify their color directly rather than going through the color table. In order to avoid confusion, I normalize all color values in Spreadsheet::ParseXLSX to their string RGB format ("#0088ff"). This affects the Fill, BdrColor, and BdrDiag properties of formats, and the Color property of fonts. Note that the default color is represented by undef (the same thing that ColorIdxToRGB would return).


Spreadsheet::ParseExcel doesn't support formulas. Spreadsheet::ParseXLSX provides basic formula support by returning the text of the formula as part of the cell data. You can access it via $cell->{Formula}. Note that the restriction still holds that formula cell values aren't available unless they were explicitly provided when the spreadsheet was written.


Large spreadsheets may cause segfaults on perl 5.14 and earlier

This module internally uses XML::Twig, which makes it potentially subject to Bug #71636 for XML-Twig: Segfault with medium-sized document on perl versions 5.14 and below (the underlying bug with perl weak references was fixed in perl 5.15.5). The larger and more complex the spreadsheet, the more likely to be affected, but the actual size at which it segfaults is platform dependent. On a 64-bit perl with 7.6gb memory, it was seen on spreadsheets about 300mb and above. You can work around this adding XML::Twig::_set_weakrefs(0) to your code before parsing the spreadsheet, although this may have other consequences such as memory leaks.

Worksheets without the dimension tag are not supported
Intra-cell formatting is discarded
Diagonal border styles are ignored

In addition, there are still a few areas which are not yet implemented (the XLSX spec is quite large). If you run into any of those, bug reports are quite welcome.

Please report any bugs to GitHub Issues at


Spreadsheet::ParseExcel: The equivalent, for XLS files.

Spreadsheet::XLSX: An older, less robust and featureful implementation.
