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.

How to use JavaScript Code Formatter

  1. Paste or type your input into the editor on the left.
  2. Leave the defaults, or tweak them if the tool exposes options.
  3. The result appears on the right as you type.
  4. Copy the output or download it.

This tool runs in your browser. Your input is not uploaded or stored.

Use it from the API

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.
