JSON to Go Struct Converter

Generate Go structs from sample JSON when you need typed request models, response payloads, or fixture definitions without hand-writing every field. Typify infers nested structs, slices, and exported Go field names automatically.

That makes it useful for backend prototyping, API client work, and debugging unfamiliar payloads when you want a fast starting point for Go code.

Go structs

type Root struct {
	Service Service `json:"service"`
}

type Service struct {
	Id float64 `json:"id"`
	Name string `json:"name"`
	Healthy bool `json:"healthy"`
	Owners []Owner `json:"owners"`
}

type Owner struct {
	Name string `json:"name"`
	Email string `json:"email"`
}

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"
      }
    ]
  }
}

Go output

type Root struct {
	Service Service `json:"service"`
}

type Service struct {
	Id float64 `json:"id"`
	Name string `json:"name"`
	Healthy bool `json:"healthy"`
	Owners []Owner `json:"owners"`
}

type Owner struct {
	Name string `json:"name"`
	Email string `json:"email"`
}
