How It Works

The rAnDoM CaSe converter takes each letter in your text and randomly decides whether it should be uppercase or lowercase. Numbers, symbols, and whitespace are left unchanged. Each conversion produces a different result, giving your text a unique chaotic appearance every time.

This style is commonly associated with the "Mocking SpongeBob" meme and is used across social media to convey sarcasm or mockery. It is also known as "sponge case" or "sarcasm case."
