This is a wrapper for the Unix command diff. It assumes that each input file is an Office spreadsheet (.ods, .xls, or .xlsx) and tries to convert the file to a directory of CSV files (where each CSV file is converted from a single worksheet) using xlsx2csv. It then passes the converted directories to diff -ruN command. Thus, formatting differences will not be diff'ed.
These are options that are interpreted by diff-xls-text and not passed to diff.
Please specify these options before file names.
Transpose CSV first using csv-transpose from App::CSVUtils. This allows you to do column-based instead of row-based diff.
If set to true, do not cleanup temporary directories.
String. Can be used to set path to diff command. See also "DIFF_XLS_TEXT_DIFF_CMD" which takes precedence.
String. Can be used to set path to diff command. The defaultl is diffwc if available in PATH, or diff. Takes precedence over "DIFF_CMD".

To contribute, you can send patches by email/via RT, or send pull requests on GitHub.
Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via:
% prove -l
If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps required beyond that are considered a bug and can be reported to me.
