The output can be pretty printed with the MarshalIndent function.

package main

import (

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

func main() {

    employees := []Employee{
        {Id: 2, FirstName: "Amir", LastName: "Khan", Email: "Amir@gmail.com"},
        {Id: 3, FirstName: "Lucy", LastName: "Smith", Email: "Smith@gmail.com"},
        {Id: 4, FirstName: "David", LastName: "Brown", Email: "David@gmail.com"},

    json_data2, err := json.MarshalIndent(employees, "", "	")

    if err != nil {
