About the Alternating Case Converter
Alternating caps is the written form of a sarcastic voice, made universal by the Mocking SpongeBob meme in 2017. Typing it by hand is genuinely tedious — which is rather the point of the joke, and also the reason a tool exists.
Paste the text and the pattern is applied letter by letter. You can choose whether the first letter is capital or lowercase, whether the alternation continues across word boundaries or resets at each new word, and whether digits and punctuation count as positions in the pattern. Those three switches cover every variant of the style people actually use.
Key features of the Alternating Case Converter
Starts on either case
Begin with a capital or a lowercase letter — the two read differently and people have preferences.
Per-word or continuous
Let the pattern run through the whole text, or restart it at every word for a more regular look.
Punctuation handling
Choose whether spaces and punctuation consume a step in the pattern or are skipped over.
Real letters, not symbols
The output is ordinary text, so it works everywhere and is not the broken Unicode a font generator produces.
Works at any length
One word or a whole paragraph — the pattern applies the same way and copies in one click.

Frequently asked questions
The Mocking SpongeBob meme, which spread in 2017 and paired a picture of the character with text in alternating caps to indicate a sarcastic, mimicking tone. The convention had existed online for years before that but the meme made it universal.
Real text. Every character is an ordinary letter, just with the case alternating, so it works everywhere and stays readable to screen readers — unlike the Unicode "fancy font" generators.
Only if you want it to. By default the pattern advances on letters alone, so spaces and punctuation do not consume a step, which keeps the effect even across words.
No. It is deliberately hard to read, screen readers pronounce it oddly, and it reads as sarcasm to anyone who recognises it. Keep it to jokes and memes.
