Why Generate TypeScript Interfaces?
TypeScript interfaces provide type safety for your JavaScript code. Instead of manually writing interfaces for API responses, paste the JSON and get accurate TypeScript types instantly. This saves time and reduces type errors.
How It Works
Our generator analyzes your JSON structure, detects types (string, number, boolean, arrays, nested objects), and produces clean TypeScript interface definitions. It handles nested objects, arrays of mixed types, and optional fields.
API Access
Use our REST API: POST /api/generate/typescript-interface with {"json_input": "...", "interface_name": "MyType"}. Free for 100 calls/day.
