JSON to TypeScript

Convert JSON data to TypeScript interfaces with inferred types and nested support

TypeScript interfaces will appear here...
How it works: Paste your JSON data and this tool generates TypeScript interfaces with inferred types. Nested objects create nested interfaces, arrays infer element types, and primitives map to string, number, or boolean. Enable "Optional fields" to make all properties optional with ?.
