General

I am always open to improvements and suggestions. Use issues

Style

I will never accept pull request that do not strictly conform to my style, however you might hate it. You can read the reasoning behind my preferences.

I really do not care about mixed spaces and tabs in (leading) whitespace

Perl::Tidy will help getting the code in shape, but as all software, it is not perfect. You can find my preferences for these in .perltidy and .perlcritic.

Requirements

The minimum version required to use this module is stated in Makefile.PL. That does however not guarantee that it will work for all underlying parsers, as they might require newer perl versions.

New parsers

I am all open to support new parsers. The closer the API is to that of Spreadsheet::ParseExcel, the easier it will be to support it.
