TypeScript Beautifier
Format and beautify TypeScript code with configurable indentation.
About This Tool
The TypeScript Formatter beautifies TypeScript code by applying consistent indentation. Paste minified or poorly indented TypeScript and get clean, readable output with 2 or 4 space indentation. All formatting runs in your browser — no code is sent to any server.
This tool uses an indentation-based reflow algorithm that tracks brace, bracket, and parenthesis depth. For full TypeScript-aware formatting with Prettier rules (type annotations, generics, decorators), use your IDE's built-in formatter. This tool is best for quick reformatting on the go.
How to Use
- Paste your TypeScript code into the input area, or click Sample to load an example.
- Choose your indent size: 2 spaces or 4 spaces.
- Click Format to apply formatting.
- Click Copy to copy the formatted output to your clipboard.
Use Cases
Developers copy minified TypeScript from build output or stack overflow answers and want to read it quickly. Code reviewers paste snippets from PRs to format before sharing in chat or documentation. Students learning TypeScript format textbook examples to understand the structure. Developers working without an IDE (on a tablet, phone, or Chromebook) need a quick online formatter.
FAQ
- Does this format generics correctly? — Basic generics are handled. Complex chained generics or conditional types may not format perfectly; use Prettier for those cases.
- Can I format JavaScript with this tool? — Yes. TypeScript is a superset of JavaScript, so valid JavaScript is also valid input.
- Is this the same as Prettier? — No. Prettier does full AST-aware formatting. This tool does indentation-based reflow, which is faster but less precise.
