Format JavaScript Code for Readability

Our JS Formatter takes minified or messy JavaScript and applies proper formatting with configurable indentation. It handles strings, template literals, comments, and nested blocks correctly.

  • Fast and local — the transform happens in your browser, so there's no round-trip and no waiting.
  • Private by default — your input never leaves your device.
  • Accurate — the same, well-tested logic powers both this page and the public API.
  • Free — unlimited use in the browser, with an optional API for automation.

The endpoint returns a JSON envelope ({ ok, data, meta }) and costs 1 credit per successful call. Try it in the playground or browse the full API reference.
