Today, I will show you how do I convert a json string to struct in golang, as above mentioned I’m going to use json.Unmarshal() with byte method.

Let’s start our Golang convert json to struct example

main.go

package main
  
import (
    "encoding/json"
    "fmt"
)

type Domain struct {
    Id        int
    Name      string
}
  
// main function
func main() {
  
    var domain Domain
  
    Data := []byte(`{
        "Id": 1,  
        "Name": "Infinitbility"
    }`)
  
    err := json.Unmarshal(Data, &domain)
  
    if err != nil {
        fmt.Println(err)
    }
  
    // printing details of
    // decoded data
    fmt.Println("Struct is:", domain)
    fmt.Println("Name is:", domain.Name)
}

In the above example, we have converted the json value to a struct and printed in golang console. let’s check the output.

Output

Struct is: {1 Infinitbility}
Name is: Infinitbility

I hope it helps you, All the best 👍.
