Today, I will show you how do I convert a map 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 map with an assignable variable in json.Marshal() method.

Let’s start our Golang convert map to json example

main.go

package main

import (
    "encoding/json"
    "fmt"
)

func main() {
    a := make(map[int]string)

    a[1] = "aGuideHub"
    a[2] = "sortoutcode"
    a[3] = "Infinitbility"

    j, err := json.Marshal(a)
    if err != nil {
        fmt.Printf("Error: %s", err.Error())
    } else {
        fmt.Println(string(j))
    }
}

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

Output

{"1":"aGuideHub","2":"sortoutcode","3":"Infinitbility"}
