JSON to TypeScript Interface Generator

Paste a sample JSON payload — an API response, a config object — and get real TypeScript interface definitions back. Nested objects are broken out into their own named interfaces automatically, and arrays are typed from their first element.

How to use it

  1. Paste your source into the panel — or click Sample to see it work instantly.
  2. The JSON to TypeScript Interface mode is pre-selected for you.
  3. Copy or download the result — nothing is ever uploaded, it's all done locally in your browser.

Frequently asked questions

How are nested object names chosen?

Nested interfaces are named from the property key that contains them (e.g. a "user" field with an object becomes interface User), de-duplicated automatically if the same shape repeats.

Does it detect union types?

For arrays with mixed element types it generates a union type, e.g. (string | number)[].

Does it handle deeply nested JSON?

Yes, nesting is unwound recursively into separate interfaces at any depth.
