JSON to Rust — Generate Serde-Compatible Structs

Writing Rust structs for API responses means a lot of boilerplate: #[derive(Serialize, Deserialize)], #[serde(rename = "...")] for every snake_case/camelCase mismatch, Option<T> for nullable fields, Vec<T> for arrays. This tool generates all of that for you.

Paste your JSON and get back a complete Rust module with serde-annotated structs. Nested objects become separate structs in the same file. The output compiles with serde = { features = ["derive"] } in your Cargo.toml with no changes needed.

❓ Frequently Asked Questions

Is processing on json-to-rust.html private and secure?

Is JSON Workbench free to use for JSON to Rust Struct Generator?

Yes, JSON Workbench is completely free for commercial and personal developer use with zero registration or payload limits.

Can I copy or download the generated output?

Yes! You can instantly copy the output code to your clipboard or download it as a structured file.
