How to Use JSON to TypeScript
This tool helps you quickly generate TypeScript type definitions from JSON data. Simply paste your JSON sample, give it a name, and the tool will automatically create strongly typed interfaces for your application.
Why Use TypeScript Types?
Strong typing in TypeScript provides better IDE autocomplete, catches errors at compile-time, and makes your code more maintainable. By automatically generating types from JSON, you ensure your frontend code matches your backend API contract.
Nested Objects and Arrays
The generator intelligently handles nested objects and arrays, creating appropriate type definitions for complex JSON structures. Arrays of primitives are detected and typed correctly (e.g., `number[]`, `string[]`).
Integration with Frameworks
The generated TypeScript interfaces work seamlessly with React, Vue, Angular, and other frameworks. Use them as prop types in React components, state types, or API response models.
Common Use Cases
- API response typing
- Database record typing
- Configuration file typing
- GraphQL query response typing
