How to use JSON to TypeScript
- Add your input or choose Try sample.
- Review the options and select Run.
- Inspect the result, then copy or download the exact output.
What are the limits of JSON to TypeScript?
Inference describes the supplied sample, not a validated API contract. Empty arrays become unknown[]. Review optional fields and domain constraints. Inputs stay in browser memory. Nothing is sent or saved automatically; clipboard and exports are explicit.
