JSON to TypeScript Interface

Generate a TypeScript interface or type from JSON.

JSON

TypeScript

interface Address {
  city: string;
  zip: string;
}

interface Root {
  name: string;
  age: number;
  active: boolean;
  score: number;
  tags: string[];
  address: Address;
}

Types are inferred from the sample JSON — check them against your real data, since a single sample can't capture every case (e.g. optional or nullable fields).
