JSON to Rust Struct Converter

Convert sample JSON into Rust structs when you need a fast starting point for API clients, config loaders, or internal tools. Typify infers nested structs, Vec<T> arrays, and Option<T> fields for nullable values automatically.

The generated output is geared toward common serde workflows, with derive macros and public fields that you can paste into Rust services, CLIs, or data-processing code with minimal cleanup.

Rust structs

use serde::{Deserialize, Serialize};

#[derive(Debug, Serialize, Deserialize)]
pub struct Root {
    pub service: Service,
}

#[derive(Debug, Serialize, Deserialize)]
pub struct Service {
    pub id: f64,
    pub name: String,
    pub healthy: bool,
    pub owners: Vec<Owner>,
    pub regions: Vec<String>,
}

#[derive(Debug, Serialize, Deserialize)]
pub struct Owner {
    pub name: String,
    pub email: Option<String>,
}

Example

Start with the sample below, then replace it with your own data to generate output instantly.

Input JSON

{
  "service": {
    "id": 17,
    "name": "typify",
    "healthy": true,
    "owners": [
      {
        "name": "Ada",
        "email": "ada@example.com"
      },
      {
        "name": "Lin",
        "email": null
      }
    ],
    "regions": ["us-east-1", "eu-west-1"]
  }
}

Rust output

use serde::{Deserialize, Serialize};

#[derive(Debug, Serialize, Deserialize)]
pub struct Root {
    pub service: Service,
}

#[derive(Debug, Serialize, Deserialize)]
pub struct Service {
    pub id: f64,
    pub name: String,
    pub healthy: bool,
    pub owners: Vec<Owner>,
    pub regions: Vec<String>,
}

#[derive(Debug, Serialize, Deserialize)]
pub struct Owner {
    pub name: String,
    pub email: Option<String>,
}
