How to convert String to Uppercase in Go ?

Answer

To convert a string to uppercase in Go, you can use the strings.ToUpper() function from the strings package.

✐ Examples

1 Uppercase of "Hello World" String

In this example,

We declare a variable named str1 with a string value of "Hello World".
We then use the strings.ToUpper() function to convert it to uppercase and store the result in the variable upperCaseStr1.
The strings.ToUpper() function returns a new string with all characters converted to uppercase.
Finally, we print the value in upperCaseStr1.

Go Program

package main

import (
    "fmt"
    "strings"
)

func main() {
    str1 := "Hello World"
    upperCaseStr1 := strings.ToUpper(str1)
    fmt.Println("Uppercase of given string is:", upperCaseStr1)
}

Output

Uppercase of given string is: HELLO WORLD

2 Uppercase of "apple" String

In this example,

We declare a variable named str2 with a string value of "apple".
We then use the strings.ToUpper() function to convert it to uppercase and store the result in the variable upperCaseStr2.
The strings.ToUpper() function returns a new string with all characters converted to uppercase.
Finally, we print the value in upperCaseStr2.

Go Program

package main

import (
    "fmt"
    "strings"
)

func main() {
    str2 := "apple"
    upperCaseStr2 := strings.ToUpper(str2)
    fmt.Println("Uppercase of given string is:", upperCaseStr2)
}

Output
