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

Let’s start our Golang convert json to string example

main.go

package main

import (
	"encoding/json"
	"fmt"
)

type Iot struct {
	Id   int    `json:"id"`
	Name string `json:"name"`
}

func main() {
	iot := Iot{
		Id:   1,
		Name: "infinitbility",
	}

	// Context is []byte, so you can keep it as string in DB
	fmt.Println("ctx:", iot)

	// Marshal back to json (as original)
	out, _ := json.Marshal(&iot)
	fmt.Println(string(out))
}

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

Output

ctx: {1 infinitbility}
{"id":1,"name":"infinitbility"}

I hope it helps you, All the best 👍.
