JSON to TypeScript
Turn JSON examples into TypeScript interfaces
ABOUT
What is JSON to TypeScript?
Convert a JSON object into readable TypeScript interfaces and primitive types. It infers nested objects locally in your browser and does not upload sample data.
ABOUT US
Small tools, built for the web.
Utilities that run entirely in your browser. No install, no signup, and your data never leaves your machine.
FAQ
Questions, answered.
Does this generate a complete TypeScript schema?＋
It creates interfaces from the example JSON you provide. Optional fields and variations across multiple array items are not inferred automatically.
