NAME

6       Spreadsheet::ParseXLSX - parse XLSX files
7

VERSION

9       version 0.27
10

SYNOPSIS

12         use Spreadsheet::ParseXLSX;
13
14         my $parser = Spreadsheet::ParseXLSX->new;
15         my $workbook = $parser->parse("file.xlsx");
16         # see Spreadsheet::ParseExcel for further documentation
17

DESCRIPTION

19       This module is an adaptor for Spreadsheet::ParseExcel that reads XLSX
20       files.  For documentation about the various data that you can retrieve
21       from these classes, please see Spreadsheet::ParseExcel,
22       Spreadsheet::ParseExcel::Workbook, Spreadsheet::ParseExcel::Worksheet,
23       and Spreadsheet::ParseExcel::Cell.
24

METHODS

26   new(%opts)
27       Returns a new parser instance. Takes a hash of parameters:
28
29       Password
30           Password to use for decrypting encrypted files.
31
32   parse($file, $formatter)
33       Parses an XLSX file. Parsing errors throw an exception. $file can be
34       either a filename or an open filehandle. Returns a
35       Spreadsheet::ParseExcel::Workbook instance containing the parsed data.
36       The $formatter argument is an optional formatter class as described in
37       Spreadsheet::ParseExcel.

INCOMPATIBILITIES

40       This module returns data using classes from Spreadsheet::ParseExcel, so
41       for the most part, it should just be a drop-in replacement. That said,
42       there are a couple areas where the data returned is intentionally
43       different:
44
45       Colors
46           In Spreadsheet::ParseExcel, colors are represented by integers
47           which index into the color table, and you have to use
48           "Spreadsheet::ParseExcel->ColorIdxToRGB" in order to get the actual
49           value out. In Spreadsheet::ParseXLSX, while the color table still
50           exists, cells are also allowed to specify their color directly
51           rather than going through the color table. In order to avoid
52           confusion, I normalize all color values in Spreadsheet::ParseXLSX
53           to their string RGB format ("#0088ff"). This affects the "Fill",
54           "BdrColor", and "BdrDiag" properties of formats, and the "Color"
55           property of fonts. Note that the default color is represented by
56           "undef" (the same thing that "ColorIdxToRGB" would return).
57
58       Formulas
59           Spreadsheet::ParseExcel doesn't support formulas.
60           Spreadsheet::ParseXLSX provides basic formula support by returning
61           the text of the formula as part of the cell data. You can access it
62           via "$cell->{Formula}". Note that the restriction still holds that
63           formula cell values aren't available unless they were explicitly
64           provided when the spreadsheet was written.

BUGS

67       Large spreadsheets may cause segfaults on perl 5.14 and earlier
68           This module internally uses XML::Twig, which makes it potentially
69           subject to Bug #71636 for XML-Twig: Segfault with medium-sized
70           document <https://rt.cpan.org/Public/Bug/Display.html?id=71636> on
71           perl versions 5.14 and below (the underlying bug with perl weak
72           references was fixed in perl 5.15.5). The larger and more complex
73           the spreadsheet, the more likely to be affected, but the actual
74           size at which it segfaults is platform dependent. On a 64-bit perl
75           with 7.6gb memory, it was seen on spreadsheets about 300mb and
76           above. You can work around this adding XML::Twig::_set_weakrefs(0)
77           to your code before parsing the spreadsheet, although this may have
78           other consequences such as memory leaks.
79
80       Worksheets without the "dimension" tag are not supported
81       Intra-cell formatting is discarded
82       Shared formulas are not supported
83           Shared formula support will require an actual formula parser and
84           quite a bit of custom logic, since the only thing stored in the
85           document is the formula for the base cell - updating the cell
86           references in the formulas in the rest of the cells is handled by
87           the application. Values for these cells are still handled properly.
88
89       In addition, there are still a few areas which are not yet implemented
90       (the XLSX spec is quite large). If you run into any of those, bug
91       reports are quite welcome.
