Go - Convert JSON to Struct

In the previous source code example, we have seen how to convert Struct to JSON in Golang. In this source code example, we show how to convert JSON to Struct in Golang with an example.

JSON (JavaScript Object Notation) is a lightweight data interchange format.

In Golang, the encoding/json package implements the encoding and decoding of JSON.

Go - Convert JSON to Struct

In this source code example, we show how to convert JSON to Struct in Golang :

package main

import (
    "encoding/json"
    "fmt"
    "log"
)

type Employee struct {
    Id         int
    FirstName       string
    LastName string
	Email string
}

func main() {

    var e1 Employee

    data := []byte(`{"Id": 1, "FirstName": "John", "LastName": "Cena", "Email" : "john@gmail.com"}`)

    err := json.Unmarshal(data, &e1)

    if err != nil {

        log.Fatal(err)
    }

    fmt.Println("Struct is:", e1)
    fmt.Println("FirstName: ", e1.FirstName)
    fmt.Println("LastName: ", e1.LastName)
    fmt.Println("Email: ", e1.Email)
}

Output: 

Struct is: {1 John Cena john@gmail.com}
FirstName:  John
LastName:  Cena
Email:  john@gmail.com
