Paste any JSON and get ready-to-use C++ structs. Types are inferred recursively: whole numbers become int (or int64_t when they exceed 32 bits), fractional numbers become double, booleans become bool, and strings become std::string. Nested objects become their own named structs derived from the field name, and arrays become std::vector of the inferred element type. The root struct name is configurable and defaults to Root.
This is a quick way to turn an API response or config sample into typed C++ models for serialization or parsing. The whole tool is plain JavaScript running locally in your browser — no build step, no server, no upload — so it is safe for private or proprietary payloads.
