JSON to TypeScript

Generate TypeScript interfaces from JSON. Paste sample JSON to get type definitions for APIs and configs.

How it works

Paste your JSON sample (e.g.

an API response or config object).

The tool generates TypeScript interfaces you can copy into your project.

Rename the interface before copying if needed.

Great for typing API clients and frontend data.
