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

To use the json.Unmarshal() method, we have first import "encoding/json" package which is built in provided by golang, then we have to pass our string as a byte array with an assignable variable.

Let’s start our Golang convert string to JSON example


package main

import (

type Message struct {
    Name    string
    Version int64

func main() {

    s := `{"name":"Android", "version":13, "code":1}`
    var m Message

    err := json.Unmarshal([]byte(s), &m)
    if err != nil {
        // panic


In the above example

  1. we have import "encoding/json" package to use json.Unmarshal() method.
  2. Created JSON ( struct ) type type Message struct to use at the time of json.Unmarshal().
  3. Created sample json string which we will convert in json.
  4. Used json.Unmarshal() method and pased byte string and message struct.

That’s how we have converted a string to JSON and printed it in the console. let’s check the output.


{"name":"Android", "version":13, "code":1}
