Format JavaScript Online
Paste minified or messy JavaScript and get properly indented, readable code. The formatter handles braces, brackets, parentheses, strings, template literals, comments, and regex literals.
How It Works
The tool uses a character-by-character parser that tracks nesting depth and correctly handles string contents (including template literals), comments, and regex literals to produce cleanly indented output.
