About the TypeScript Formatter & Beautifier
Paste a minified or hastily-written TypeScript fragment and get back structured, indented code. Type annotations (const x: string), interfaces, generics and decorators pass through the tokenizer untouched - only whitespace and line structure are normalized.
The same ASI-safe guarantee as the JavaScript formatter applies: original lines are never merged, so type-only code and interface bodies keep their exact shape. Everything runs locally, so proprietary code never leaves your machine.
How to use it
- 1Paste your TypeScript into the input.
- 2Choose 2-space or 4-space formatting.
- 3Copy the result into your .ts file.
