Generated in this page — nothing is uploaded, which matters when the sample JSON is a real API response. Remember that these types describe the sample you pasted, not the API's contract: a field absent from your sample cannot appear in the output.

Generates TypeScript interfaces from a JSON sample by merging every array element, so keys missing from some objects become optional rather than being ignored. Emits valid output for array roots, names nested interfaces, and reports what it could not infer. The interactive workspace runs in your browser, so you can review the result without creating an account.
