JSON to TypeScript Generator

Convert JSON API responses to TypeScript interfaces, Zod schemas, React Query hooks, Prisma models, and mock data β€” in seconds.

⚑ 30 Seconds

What used to take 15-20 minutes per endpoint now takes seconds. Paste JSON, click generate, done.

🎯 100% Accurate

No more typos or missed nested fields. The generator analyzes your entire JSON structure.

πŸ”„ Easy Updates

API changed? Just paste the new response and regenerate. No manual refactoring needed.

Understanding the Generated Code

Learn what each output type does and how to use them effectively in your projects.

TypeScript interfaces are the foundation of type-safe development. They catch errors at compile time, provide excellent IDE autocomplete, and serve as documentation for your data structures.

Benefits of Type-Safe API Responses:

  • Catch property access errors before runtime
  • Get intelligent autocomplete in your IDE
  • Document data structures automatically
  • Refactor with confidence using "Find All References"
  • Reduce bugs from typos and incorrect data access

πŸ’‘ Pro Tips

  • β€’Start with TypeScript + Zod β€” Generate both to get compile-time AND runtime safety.
  • β€’Use meaningful root names β€” "UserResponse" or "ProductList" are better than "ApiResponse".
  • β€’Regenerate when APIs change β€” Just paste the new response and regenerate. Much faster than manual updates.
  • β€’Review Prisma models β€” The generator makes best-effort guesses for relations. You may need to adjust for your specific database design.
