What is JSON to TypeScript?
JSON to TypeScript is a developer tool that automatically generates TypeScript interfaces and types from JSON data. Instead of manually writing type definitions for API responses, configuration files, or any JSON structure, this tool parses your JSON and produces clean, accurate TypeScript interfaces — all instantly in your browser.
It handles nested objects by creating separate interfaces, correctly types arrays by detecting element types, and supports all JSON primitives including strings, numbers, booleans, and null values. Your data never leaves your browser — everything is processed client-side.
