How JSON to Rust works

Generate Rust structs with Serde Serialize/Deserialize derives from JSON. Output is Rust-specific. Runs in your browser.

  1. 1. Paste JSON. Use a real API response so nested types come through.
  2. 2. Check the Rust output. Scan names, optionals, and nested types.
  3. 3. Copy the code. Drop it into your project and adjust if the sample was incomplete.
  • Generate Rust models from a real API JSON sample
  • Paste the output into an existing Rust project
  • Serde struct
Does it use Serde?
Yes. Structs derive Serialize and Deserialize, with rename attributes for non-snake_case keys.
