How It Works

The Code Formatter & Minifier formats code by analyzing brace and indentation structure per language. JavaScript and TypeScript use bracket-based indentation, Python detects colon-driven block boundaries, HTML nests tags by depth, and CSS structures selectors with brace tracking. Minification strips unnecessary whitespace and comments while preserving functionality. Validation checks syntax rules including JSON parsing, brace/parenthesis balancing, tag matching, keyword presence, and indentation consistency.

Everything runs locally in your browser — no code is ever sent to a server, ensuring complete privacy.
