How to use JavaScript Formatter
Format JavaScript into readable, indented code without executing it.
- Enter the text, code or network information you want to process.
- Choose the options available in the tool.
- Verify the generated result and copy it when appropriate.
Inputs are processed in your browser unless the tool explicitly states that it retrieves reference data. Verify the result against your own context before making an important decision.
Beautify JavaScript for easier review
Convert compact JavaScript into a readable layout with consistent indentation and line breaks. This is useful for examining generated snippets, reviewing bundled fragments and finding structural mistakes in deeply nested code.
Formatting is not validation
The formatter improves presentation but does not execute, lint or prove that the code is safe. Review the output carefully and run your normal tests before using it in production.
Your code remains local
Processing happens in your browser. The pasted source is not sent to our server, stored in a database or shared with a third party.
