Paste messy TypeScript and get clean readable code with consistent indentation in seconds.
Your code never leaves your browser. Everything runs locally on your device.
Messy TypeScript is hard to read and hard to debug. The TypeScript Beautifier reformats your code with consistent indentation and spacing, while keeping every type, interface, and generic exactly as you wrote it.
Unlike a plain JavaScript formatter, this tool understands TypeScript syntax, so interfaces, enums, generics, and type annotations survive formatting untouched. Everything runs in your browser, so your code is never uploaded to a server.
Yes, it is completely free with no sign up and no limits. You can beautify as much TypeScript as you like, as often as you like.
No. Beautifying only changes indentation and spacing. Your logic, types, and values stay exactly the same.
Yes. Interfaces, type aliases, generics, enums, and type annotations are preserved word for word in the output.
Yes. Pick 2 spaces or 4 spaces from the indent size option to match your project style.
No. All formatting happens in your browser on your own device, so your code never leaves your computer.
The tool still tries to format what it can, and shows a clear message if the input cannot be read, while keeping your input untouched.
When your code is readable again and ready to ship smaller, try the TypeScript minifier to shrink it for production.
