Streamlining Full-Stack Development

TypeScript has revolutionized frontend development by providing type safety. However, manually creating interfaces for complex API responses is a tedious and error-prone task. JSONGen TS Generator automates this workflow.

  • Nested Object Support: Automatically creates sub-interfaces for complex hierarchies.
  • Array Type Detection: Correct identifies arrays and their internal element types.
  • Null Safety: Handles optional fields and null values intelligently.

By paste-and-copying your JSON into our generator, you can save hours of manual typing and ensure that your frontend types are always in sync with your backend data structures.
