About JSON to Rust

Paste JSON and get Rust structs with serde derive — nested objects become their own structs, arrays become Vec<T>, optional fields become Option<T> and non-snake keys get #[serde(rename)].

Built for modeling API responses in reqwest-based services. Generation runs entirely in your browser — your JSON is never uploaded.
