TypeScript Beautifier

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. It uses an indentation-based reflow algorithm that tracks brace, bracket, and parenthesis depth.

How to Use

1. Paste your TypeScript code into the input area, or click Sample to load an example.
2. Choose your indent size: 2 spaces or 4 spaces.
3. Click Format to apply formatting.
4. Click Copy to copy the formatted output to your clipboard.

Use Cases

Developers read minified TypeScript from build output. Code reviewers format snippets before sharing. Students format examples to understand structure. Developers without an IDE use it as 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.
• 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.
