JSON to TypeScript

Turn JSON objects into TypeScript interfaces and save time when modeling APIs and frontend data.

Open JSON to TypeScript now

Opens the tool directly. Your work stays in your browser.

Private by design: The conversion happens in the browser, so your sample data stays on your device while you generate interfaces.

What it does

Generate TypeScript shapes from sample JSON so you can move from raw payloads to typed application models faster.

Good for

  • Building typed front-end models.
  • Creating interfaces from sample API data.
  • Speeding up prototyping and handoff.

Why it stays private

The conversion happens in the browser, so your sample data stays on your device while you generate interfaces.

Frequently asked questions

Is the tool safe for internal payloads?

Yes. The conversion runs in the browser, so sample data stays local.

Can it accelerate frontend work?

Yes. It is useful for creating type skeletons before real implementation.

Do I need a backend?

No. Type generation runs directly in the page without a server.
