JSON to types

Sample JSON (paste, type or drop a file)

TypeScript · from the example

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

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

export interface Order {
  id: number;
  total: number;
  gift?: boolean;
  note?: string;
}

Arrays are merged: a key missing from some items is optional, and a value that's sometimes null is nullable. Paste several examples in an array for better types.
