how to convert string to bool in golang?

Hi Friends 👋,

Welcome To aGuideHub! ❤️

To convert string to bool in golang, just use strconv.ParseBool() method and assign your value it will convert string to bool. Only you have to pass string into an ParseBool() method.

Follow the below tutorial if you are struggling with installing GO in windows.

Today, I will show you how do I convert string to bool in golang, as above mentioned I’m going to use ParseBool() way.

The strconv package provide ParseBool() method.

The ParseBool() method convert true for "1", "t", "T", "TRUE", "true", "True". and false for "0", "f", "F", "FALSE", "false", "False".

Let’s start our Golang convert string to bool example

Convert whole string into boolean example

main.go

package main

import (
	"fmt"
	"strconv"
)

func main() {
  // truth cases example
	s1 := "true"
	b1, _ := strconv.ParseBool(s1)
	fmt.Printf("%T, %v\n", b1, b1)

	s2 := "t"
	b2, _ := strconv.ParseBool(s2)
	fmt.Printf("%T, %v\n", b2, b2)
	
	s3 := "1"
	b3, _ := strconv.ParseBool(s3)
	fmt.Printf("%T, %v\n", b3, b3)

  // false cases example
	s4 := "0"
	b4, _ := strconv.ParseBool(s4)
	fmt.Printf("%T, %v\n", b4, b4)

	s5 := "F"
	b5, _ := strconv.ParseBool(s5)
	fmt.Printf("%T, %v\n", b5, b5)
	
	s6 := "false"
	b6, _ := strconv.ParseBool(s6)
	fmt.Printf("%T, %v\n", b6, b6)
}

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

Output

bool, true
bool, true
bool, true
bool, false
bool, false
bool, false
