Practical Guide
How to use JSON Interface Generator
Use a representative JSON sample to draft TypeScript interfaces for your application's data model. Review optional and nullable fields before adding the types to your codebase.
Useful situations
- Create a starter interface for a REST API response.
- Document a nested object shape shared with frontend developers.
- Spot fields that may require explicit nullability.
Step-by-step workflow
- Paste a representative JSON object or array.
- Generate the suggested TypeScript types.
- Review types against your full API specification before committing.
Sample input to try
Use the Load example button in the playground, or copy this input and adapt it.
{"user":{"id":"u1","email":"example@example.com"},"roles":["reader"],"active":true}
Important: One sample cannot reveal every optional field, enum or null case. Verify against the actual API contract.
