Unmarshal.go

package main

import (
    "encoding/json"
    "fmt"
)

type Language struct {
    Id   int
    Name string
}

func main() {

    // String contains two JSON rows.
    text := "[{\"Id\": 100, \"Name\": \"Go\"}, {\"Id\": 200, \"Name\": \"Java\"}]"
    // Get byte slice from string.
    bytes := []byte(text)

    // Unmarshal string into structs.
    var languages []Language
    json.Unmarshal(bytes, &languages)

    // Loop over structs and display them.
    for l := range languages {
        fmt.Printf("Id = %v, Name = %v", languages[l].Id, languages[l].Name)
        fmt.Println()
    }
}
