Overview

encoding/json package provides the Marshal function which can be used to convert a golang array or slice into a JSON string and vice versa.

Let’s see an example

Example

package main
import (
"encoding/json"
"fmt"
)
func main() {
a := make([]string, 2)
a[0] = "John"
a[1] = "Sam"
j, err := json.Marshal(a)
if err != nil {
fmt.Printf("Error: %s", err.Error())
} else {
fmt.Println(string(j))
}
}

Output

["John","Sam"]
