JSON to TypeScript

Generate TypeScript interfaces from a JSON sample.

Root interface name

interface Root {
  id: number;
  name: string;
  tags: string[];
}

Turn any JSON object into ready-to-use TypeScript interfaces, inferring types automatically.

Anleitung

Paste a JSON sample.
Name the root interface.
Copy the generated interfaces.

Häufige Fragen

Does it handle nested objects?: Yes, nested objects become their own interfaces.
What about empty arrays?: Empty arrays are typed as unknown[] since the item type can't be inferred.
