What does the TypeScript formatter do?

It auto-beautifies TS/TSX code: unifies indentation, adjusts line breaks, standardizes semicolon and quote styles, and formats type annotations and interface definitions. Perfect for cleaning up pasted code snippets.

Does it support TSX/JSX syntax?

Yes. TSX (TypeScript + JSX) is fully supported for React, Vue, SolidJS, and other frameworks. JSX template structures and type parameters are preserved correctly.

Is my code uploaded to a server?

No. Everything runs locally: Indent and Semicolons are processed on your device, never sent to a server. Your code never leaves your device — critical for sensitive logic or keys.

How is this different from Prettier?

Prettier requires Node.js installation and configuration, ideal for project-level formatting. This tool is a zero-install online alternative, perfect for quick snippet formatting. For full projects, use Prettier; for quick needs, this tool is more convenient.
