Why generate code from JSON?

When working with REST APIs, the JSON responses often define your data model. Instead of manually writing TypeScript interfaces, Go structs, or Pydantic models, you can paste the API response directly and have AllJSONTools generate the types automatically. This eliminates typos, saves time, and ensures your types always match the actual data shape.

All generators are 100% client-side. Your JSON, API keys, and sensitive data never leave your browser. The generated code is production-ready and follows language conventions — including proper casing, json tags in Go, Serde annotations in Rust, and @SerialName in Kotlin.
