Random case turns ordinary text into the mocking, sarcastic style made famous by the SpongeBob meme. Each letter is randomly switched to upper or lower case, so “why would I do that” becomes something like “wHy WoULd i Do ThAt”. This tool gives you both a genuinely random coin-flip and a strict alternating pattern.
How it works
The converter walks through your text one character at a time. For each alphabetic character it decides the case; everything else passes through untouched.
random mode: for each letter, flip a coin -> upper if heads, else lower
alternating mode: for each letter, toggle a flag that started false
-> letters become lower, UPPER, lower, UPPER, ...In alternating mode the toggle only advances on letters, so spaces and punctuation never throw the rhythm off. Because random mode draws a fresh coin flip for every letter, pressing Convert again produces a brand new pattern.
Tips and examples
Use alternating mode when you need a result you can reproduce exactly, for example in a saved meme template. Use random mode for a more natural, uneven mocking look. The output is plain text, so it works anywhere: chat apps, social posts, code comments, or document titles. Numbers and emoji are preserved, which keeps hashtags and handles intact.
