What Is a TypeScript Formatter?

A TypeScript Formatter is a free online tool that cleans up and restructures TypeScript code. In Beautify mode it adds consistent indentation, puts each statement on its own line, and makes nested blocks easy to follow. In Minify mode it strips all whitespace and comments to produce the smallest possible output. The formatter handles TypeScript-specific syntax including interfaces, type aliases, generics, enums, and decorators alongside all ES6+ JavaScript features.

How to Use TypeScript Formatter

  1. Choose Beautify to format TypeScript with indentation, or Minify to compress it.
  2. Select your preferred indent size: 2 or 4 spaces.
  3. Paste your TypeScript into the input panel, or click Load Sample to try an example.

  5. Click Copy to copy the result to clipboard.
