Today, I will show you how do I convert int to string in golang, as mentioned above I’m going to use the Itoa() method which is provided by the strconv package.

Let’s start our Golang convert int to string example

main.go

package main

import (
    "strconv"
    "fmt"
    "reflect"
)

func main() {
    t := strconv.Itoa(123)
    fmt.Println(t)
    fmt.Println(reflect.TypeOf(t))
}

In the above example, we have converted the int value to a string and printed in golang console. let’s check the output.

Output

123
string
