JSON sample

TypeScript interfaces

interface Root {
  id: number;
  name: string;
  active: boolean;
  score: number;
  deletedAt: null;
  roles: string[];
  profile: Profile;
  posts: Post[];
}

interface Links {
  website: string;
  verified: boolean;
}

interface Profile {
  bio: string;
  links: Links;
}

interface Post {
  title: string;
  views: number;
}

Paste a JSON sample to generate TypeScript interfaces. Nested objects become their own named interfaces, arrays infer their element type from the first item, and null values map to the null type. Everything runs in your browser.
