Convert JSON to Rust Serde Structs

Transform JSON payloads into Rust structs with Serde annotations and snake_case field mapping.

About This Tool

JSON to Rust Struct Generator converts JSON payloads into memory-safe Rust structs with Serde serialization derives (Serialize, Deserialize, Debug, Clone) and custom rename attributes.

Key Features

Full Serde Serialize/Deserialize derive support
Automatic camelCase to snake_case field renaming
Typed Vec<T>, Option<T>, i64, and f64 primitive mappings

How to Use

  1. 1Paste your JSON payload into the input area.
  2. 2Specify your root Rust struct name.
  3. 3Copy the generated Rust code.

Why Use ToolSnippet JSON to Rust Struct (Serde) Generator?

Speed up Rust backend and Actix/Axum web service development.
Automatically maps camelCase JSON keys to idiomatic snake_case Rust fields with #[serde(rename = "...")].

Tips for Best Results

  • Add serde = { version = "1.0", features = ["derive"] } to your Cargo.toml dependencies

Frequently Asked Questions

What derives are included on generated structs?

Structs include #[derive(Default, Debug, Clone, PartialEq, Serialize, Deserialize)] for full standard library ergonomics.
