Convert a JSON object to a C# Class automatically. Paste JSON and get typed C# code instantly. Free online tool.
The JSON to TypeScript Converter is a productivity booster for frontend and backend developers working with APIs. Instead of manually typing out TypeScript interfaces for complex JSON responses, simply paste your JSON data here to get instant, accurate type definitions. The tool handles nested objects, arrays of objects, and optimal type inference (string, number, boolean, etc.). It generates modern TypeScript code (interfaces/types) that you can copy directly into your project, ensuring type safety and reducing potential runtime errors caused by mismatched data structures.
