Parsing JSON data without concrete struct in Go

```go

package main

import (

	"encoding/json"

	"log"

)

var sampleJson = `{

	"username": "herr.wayne",

	"password": "L3akyPa5sw0rd!",

	"name": "Herr Wayne",

	"website": "https://example.de",

	"number": 123

}`

func main() {

	rawData := []byte(sampleJson)

	var payload interface{}                  //The interface where we will save the converted JSON data.

	err := json.Unmarshal(rawData, &payload) // Convert JSON data into interface{} type

	if err != nil {

		log.Fatal(err)

	}

	m := payload.(map[string]interface{}) // To use the converted data we will need to convert it into a map[string]interface{}

	log.Printf("Username: %s", m["username"].(string))

	log.Printf("Password: %s", m["password"].(string))

	log.Printf("Name: %s", m["name"].(string))

	log.Printf("Website: %s", m["website"].(string))

	log.Printf("Number: %d", int(m["number"].(float64)))

}
