Mocking case

Mocking case, also known as SpongeBob mocking or sponge case, is a humorous text style that alternates between uppercase and lowercase letters. The term comes from the SpongeBob SquarePants character who mocked others by speaking this way in the show. Paste any text and this tool converts it instantly, flipping every letter between upper and lower while keeping spaces, punctuation, numbers and line breaks untouched.

The rule is straightforward: start with a lowercase letter, then toggle to uppercase, then lowercase again, and so on. Non-letter characters like spaces, numbers, emoji and symbols do not count toward the alternation — they pass through unchanged and don't affect the letter toggle. For example, "hello world" becomes "hElLo WoRlD" because the space doesn't advance the counter, so the 't' after the space lands on an uppercase position.

Mocking case is popular on social media as a playful way to express mockery, sarcasm or humorous exaggeration. The alternating capitals create a distinctive visual rhythm that reads as mocking or dismissive tone without using words alone. Capitalization is preserved where possible, so mixed-case input still produces readable output. Anything that is not a letter — digits, accented characters, emoji, symbols — passes through as-is.

Everything runs entirely in your browser with no uploads, making it safe for social media posts, joke messages, or creative writing. The live tally under the output counts how many letters were alternated. Copy the result, download it as a .txt file, or send it to another tool to combine effects.
