To convert interface to map in golang, use interface.(map) method, it will convert interface to map. You have to only pass your map type in interface.

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

Let’s start our Golang convert interface to map example

main.go

package main

import (
	"encoding/json"
	"fmt"
)

func main() {

	b := []byte(`{"firstname":"aGuide", "lastname": "hub"}`)

	var f interface{}
	json.Unmarshal(b, &f)

	myMap := f.(map[string]interface{})

	fmt.Println(myMap["lastname"])
}
