Json To Typescript Interface
JSON to TypeScript is a free online Data Conversion Tools tool that generate TypeScript interfaces from a JSON sample, including nested objects and arrays instantly in your browser. Paste your data, adjust the options and get the result in real time — no installation, no sign-up, and nothing is ever uploaded to a server. The conversion runs both ways in your browser: input format A on the left, format B on the right, instantly.
How to use
Using JSON to TypeScript takes three steps:
- Paste your data into the input box (or load the example).
- Configure the options to match your target format or scenario.
- Copy, download or inspect the output — it updates live as you type.
- The conversion runs both ways in your browser: input format A on the left, format B on the right, instantly.
