How to convert JSON to TypeScript interfaces
Paste a JSON sample and generate TypeScript interfaces in your browser.
Why generate types from JSON?
API responses rarely ship with types. Inferring interfaces from a real payload is faster than writing them by hand and helps catch typos in nested fields.
Steps
1) Open JSON → TypeScript. 2) Paste a representative JSON object or array. 3) Click Run. 4) Copy the generated interfaces into your project. Arrays and nested objects become named types.
