How to Use JSON to Multi-Language Models

  1. Paste a representative JSON payload or array of objects into the editor.
  2. Select your target language (Go, Python, Rust, C#, or Kotlin).
  3. Customize the Root Model Name if needed.
  4. Copy the generated typed model definitions into your codebase.

Frequently Asked Questions

Which programming languages are supported?

The generator currently supports Go (Golang structs with JSON tags), Python (Pydantic v2 BaseModels), Rust (Serde structs), C# (Records with JsonPropertyName), and Kotlin (Data classes).

How are nested objects and arrays handled?

Nested JSON objects are extracted into separate, typed structs or classes with camel/pascal casing, and array item types are automatically inferred.

Is my JSON data uploaded to any server?

No. The code generation runs 100% locally inside your browser using client-side JavaScript.
