Instantly convert JSON API responses into structurally perfect TypeScript Interfaces.
Why Use This TypeScript Generator?
Stop manually typing out massive API models for your React or Angular apps. Paste any JSON response, and our engine instantly generates the strict structural blueprints required by TypeScript.
Complex APIs return nested objects and arrays within arrays. Our intelligent parser recursively maps every depth layer, automatically naming and creating sub-interfaces (like number[][]) for you.
If an array contains objects with different properties (e.g., event logs), our advanced engine scans the entire array and merges them to ensure no optional properties are ever missed in the interface.
Unlike backend languages, TypeScript interfaces must exactly match the JSON keys for JSON.parse() to work correctly. Our engine safely wraps invalid identifiers in quotes while preserving your original API casing.
Easily rename the top-level root object right from the toolbar (e.g., UserResponse). All dependent nested interfaces and arrays will inherit your custom naming convention seamlessly.
Pasting sensitive user data or proprietary API payloads? Your JSON is strictly secure. The entire parsing and generation engine runs locally in your browser and is never sent to our servers.
