JSON to TypeScript
About JSON to TypeScript
Paste any JSON object or array and instantly generate TypeScript interfaces with proper types, optional properties, and nested interfaces. Saves hours of manual typing.
How To Use
- Paste or load the code, payload, or data you want to inspect into JSON to TypeScript.
- Run the formatter, validator, converter, or generator shown in the tool controls and JSON to TypeScript processes it in your browser.
- Copy the cleaned output to your clipboard, or export it as a file when the tool provides a download.
Example
Input: A snippet of code, a JSON payload, or a data string.
Output: Formatted, validated, converted, or generated output you can paste straight back into your project.
Who Uses JSON to TypeScript
- Developers who prefer private, browser-only tools for formatting, validation, and data work.
- Engineers who need fast local tools without installing anything or uploading code.
- Teams that want private — files and text stay on your device and are never uploaded to a server.
