How to convert Header Case String to Constant Case String?

To convert Header Case String to Constant Case String, we need to split the string into words, then convert each word to constant case, then join the words together.

Example

Let's convert the string "Hello World" to Constant Case String.

First, we need to split the string into words.

String	Words
Hello World	Hello, World

Now, we need to convert each word to constant case.

Words	Constant Case Words
Hello, World	HELLO, WORLD

Finally, we need to join the words together. In this case, the final Constant Case String is HELLO_WORLD. This is the Constant Case String representation of the string "Hello World".
