Today, I will show you how do i convert struct to JSON in golang, as above mentioned I’m going to use the json.Marshal() method.

To use the json.Marshal() method, we have first import "encoding/json" package which is built in provided by golang, then we have to pass our struct with assignable variable in json.Marshal() method.

Let’s start our Golang convert struct to JSON example

main.go

package main

import (
    "encoding/json"
    "fmt"
)

type Message struct {
    Name    string
    Version int64
    Code    int64
}

func main() {

    s := &Message{Name: "Android", Version: 13, Code: 1}

    b, err := json.Marshal(s)
    if err != nil {
        fmt.Println(err)
        return
    }
    fmt.Println(string(b))
}

In the above example, we have converted a object to JSON and printed it in the console. let’s check the output.

Output

{"Name":"Android","Version":13,"Code":1}

I hope it helps you, All the best 👍.
