About JSON → TypeScript
Convert any JSON to TypeScript interfaces, type aliases, or Zod schemas instantly — with smart type inference for emails, UUIDs, dates, and URLs.
How to use JSON → TypeScript
- 1Paste your JSON data in the input panel.
- 2View the automatically generated TypeScript output in the right panel.
- 3Review the inferred types — the tool detects strings, numbers, booleans, arrays, and nested objects.
- 4Check smart type inferences for emails, UUIDs, dates, and URLs.
- 5Copy the TypeScript output and use it in your project.
Tips
- The tool handles nested objects and arrays of mixed types — it generates union types when appropriate.
- Use the generated interfaces as a starting point and refine with optional properties or custom types.
- Upgrade to Starter+ to unlock Zod schema generation for runtime validation.
