About this JSON to TS Converter

When integrating with external APIs, creating accurate TypeScript types for the payloads is essential but incredibly time-consuming. This tool automates the process by analyzing your raw JSON and generating clean, reusable TypeScript interfaces.

This converter runs entirely in your browser. Unlike other online generators, your confidential payloads and data structures are never transmitted to our servers. Your data and your generated interfaces are 100% private.

Features

  • Nested structure extraction to separate interfaces.
  • Array types parsing and unification.
  • Safe key handling for non-standard property names.
  • Customizable root interface name.
