JSON → TypeScript

Generate TypeScript interfaces from a JSON sample

Inferred from sample

Types are inferred from the sample only. Optional fields, nullable values, and union types may be missed — always review before using.

Root interface name

Input JSON

Output TypeScript

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

export interface Root {
  id: number;
  name: string;
  email: string;
  tags: string[];
  address: Address;
}

Verify outputs before using in production. No warranty — see Terms.
