Spreadsheet::ParseXLSX - parse XLSX files
version 0.35
use Spreadsheet::ParseXLSX;
my $parser = Spreadsheet::ParseXLSX->new;
my $workbook = $parser->parse("file.xlsx");
# see Spreadsheet::ParseExcel for further documentationThis module is an adaptor for Spreadsheet::ParseExcel that reads XLSX files. For documentation about the various data that you can retrieve from these classes, please see Spreadsheet::ParseExcel, Spreadsheet::ParseExcel::Workbook, Spreadsheet::ParseExcel::Worksheet, and Spreadsheet::ParseExcel::Cell.
Returns a new parser instance. Takes a hash of parameters:
Password
Password to use for decrypting encrypted files.
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.
The $formatter argument is an optional formatter class as described in Spreadsheet::ParseExcel.
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:
Colors
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).
Formulas
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
Shared formulas are not supported
Shared formula support will require an actual formula parser and quite a bit of custom logic, since the only thing stored in the document is the formula for the base cell - updating the cell references in the formulas in the rest of the cells is handled by the application. Values for these cells are still handled properly.
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 https://github.com/MichaelDaum/spreadsheet-parsexlsx/issues.
