JSON to Rust Converter

How to use

1. Paste JSON input from your API payload or sample document.
2. Select your output target and model options.
3. Generate, review, and copy the result.

Benefits

• Handles nested objects and arrays from API responses.
• Reduces manual model writing and naming inconsistencies.
• Works instantly in browser with copy-ready output.

Best use cases

• Generate Rust structs for serde JSON parsing quickly.
• Bootstrap typed models for APIs and CLI tools.
• Reduce manual struct authoring for nested payloads.

Type mapping notes

• JSON fields map to Rust struct fields with inferred scalar types.
• Nested objects map to nested Rust structs.
• Arrays map to Vec<T> with inferred element types.

Implementation tips

• Review integer width and float precision for production payloads.
• Add serde attributes for key renames when needed.
• Organize generated models in a dedicated module tree.

Sample JSON

{
  "id": 101,
  "name": "Ada Lovelace",
  "active": true,
  "roles": ["admin", "editor"],
  "profile": {
    "email": "ada@example.com",
    "score": 9.8
  }
}

Sample output

#[derive(Debug, Serialize, Deserialize)]
pub struct UserModel {
    pub id: i64,
    pub name: String,
    pub active: bool,
    pub roles: Vec<String>,
}
