Today, I will show you how do I convert a map to string in golang, as above mentioned I’m going to use json.Marshal() and string() method.

To use the json.Marshal() method, we have first import "encoding/json" package, then we have to create json variable which we will use to assign value.

Let’s start our Golang convert map to string example

main.go

package main

import (
	"fmt"	
	"encoding/json"	// Encoding and Decoding Package
)

func main() {
  	// Create a map of key/value pairs and parses the data into JSON
	user := make(map[string]interface{})
	user["id"] = 1
	user["name"] = "James Bond"
	user["phone"] = map[string]interface{}{
	"home": "123-466-799",
	"office": "564-987-654",
	}
	user["email"] = "[email protected]"

	// Marshal the map into a JSON string.
	userData, err := json.Marshal(user)	
	if err != nil {
		fmt.Println(err.Error())
		return
	}
	
	jsonStr := string(userData)
	fmt.Println(jsonStr)
	
}

In the above example, we have converted the map to string and printed in golang console. let’s check the output.

Output

{"email":"[email protected]","id":1,"name":"James Bond","phone":{"home":"123-466-799","office":"564-987-654"}}

I hope it helps you, All the best 👍.
