}What is JSON to TypeScript Converter?
This tool automatically inspects any valid JSON object and generates typed TypeScript interfaces or type aliases with accurate property types, nested object definitions, and array primitive inference. Perfect for frontend devs working with REST or GraphQL APIs.
Key Features
- Accurate Type Inference: Detects strings, numbers, booleans, arrays, nested objects, nullables, and dates.
- Flexible Options: Toggle optional modifiers (`?`), `readonly` attributes, and customize root interface names.
- YAML Conversion: Also converts JSON into structured, indented YAML format.
- 100% Private: Runs locally in your browser with zero data retention or API calls.
Frequently Asked Questions
How does it handle nested objects and arrays?▼
Nested objects are extracted into separate, cleanly named TypeScript interfaces. Arrays of objects inspect the structure to produce uniform array element typings.
Can I use this for API response types in React / Next.js?▼
Yes! Simply paste your API JSON response, set your Root Interface Name (e.g., `UserData`), and paste the generated TypeScript definitions straight into your types file.
Is my JSON data kept confidential?▼
Absolutely. All parsing and conversion algorithms run entirely inside your browser's JavaScript engine.
