About This Tool
JavaScript formatting transforms minified or obfuscated code into readable, properly indented source. This is essential for debugging third-party code or understanding how libraries work.
Our formatter handles modern ES6+ syntax including arrow functions, template literals, destructuring, and async/await. It properly indents nested callbacks, promise chains, and complex object structures.
Choose your preferred brace style - Allman (braces on new lines) or K&R (opening brace on same line). Quote style can be normalized to single or double quotes throughout your code.
The tool preserves comments and handles edge cases like regex literals and template strings that might confuse simpler formatters.
