About JSON → TypeScript Interface Generator
The JSON → TypeScript Interface Generator creates TypeScript interfaces from JSON. Recursively generates interfaces for nested objects. Configure the root interface name. Toggle optional fields to add ? to every property. Use for API response types, config schemas, or any JSON structure. The tool infers types from your data—arrays with mixed types may produce unions. Copy the generated code into your project. Saves time when integrating with APIs or defining data models. All generation runs locally. No server calls.
