How to convert Boolean Type to String in Go?

Like most modern languages, Golang includes Boolean as a built-in type. Let's take an example, you may have a variable that contains a boolean value true. In order to convert boolean vale into string type in Golang, you can use the following methods.
FormatBool function
You can use the strconv package's FormatBool() function to convert the boolean into an string value. FormatBool returns "true" or "false" according to the value of b.

Syntax

func FormatBool(b bool) string

Example

package main

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

func main() {
	var b bool = true
	fmt.Println(reflect.TypeOf(b))

	var s string = strconv.FormatBool(true)
	fmt.Println(reflect.TypeOf(s))
}

Output

bool
string
fmt.Sprintf() method
Sprintf formats according to a format specifier and returns the resulting string. Here, a is of Interface type hence you can use this method to convert any type to string.

Syntax

func Sprintf(format string, a ...interface{}) string

Example

package main

import (
	"fmt"
	"reflect"
)

func main() {
	b := true
	s := fmt.Sprintf("%v", b)
	fmt.Println(s)
	fmt.Println(reflect.TypeOf(s))
}

Output

true
string
