mensch

A decent, non-validating CSS parser and stringifier. Current stable version is 0.3.4 (last release 2015-04-02, now in maintenance mode). Provides parse, stringify, and lex functions with support for comments and position tracking. Unlike validating parsers, mensch handles malformed CSS (mis-matched braces, missing semi-colons) without error. Differentiators: comments in AST, position info, and lenient parsing. Alternatives: PostCSS, css, csstree.
