Jaguar Code Formatter

Format messy code instantly — JavaScript, TypeScript, CSS, HTML, JSON, and GraphQL. This tool runs the same formatting engine used by millions of developers, directly in your browser. No installation, no signup, no data sent to any server. Paste, format, copy.

What languages does this formatter support?

JavaScript, TypeScript, CSS, HTML, JSON, and GraphQL. It uses industry-standard formatting rules — consistent indentation, proper spacing, clean line breaks. The same output you'd get from a local install.

Is my code uploaded to a server?

No. All formatting runs 100% in your browser. Your code never leaves your device — nothing is sent to any server. Safe for proprietary and sensitive code.

Can I customize formatting options?

Yes. Adjust tab width (2 or 4 spaces), single vs double quotes, semicolons, trailing commas, and print width. Changes apply on the next format.
