About this Tool

Convert JSON payloads into Rust structs with Serde derive annotations and rename attributes client-side.

What are Rust Serde Structs?

Serde is the industry standard serialization/deserialization framework for Rust. This tool generates structs decorated with #[derive(Default, Debug, Clone, PartialEq, Serialize, Deserialize)] and camelCase serde rename attributes for production-grade reliability.

Type Safety & Primitives

Maps numbers to i64 or f64, strings to String, booleans to bool, and null values to Option<serde_json::Value>.

Confidential Execution

All AST generation executes in local browser memory with zero network calls.

Privacy Guarantee

The JSON to Rust Struct Generator operates 100% locally in your web browser. Your JSON objects, arrays, and keys are processed entirely in-memory using Web Workers and JavaScript. No JSON data is ever transmitted across the network or stored on external servers, making it completely safe for sensitive enterprise payloads.
