What Is Alternating Case?

How Is It Different from Toggle Case?

Alternating Case changes every other character to uppercase, based on index position. Toggle Case flips the case of each existing letter — uppercase becomes lowercase and vice versa — based on the current state.

Toggle Case: HeLLo WoRLD

Pro Tip 💡

Use sparingly — alternating case is perfect for humor and emphasis, but can become hard to read if overused in long paragraphs.
