Inverse Case & aLtErNaTiNg

Two letter-by-letter formats. iNVERSE swaps every letter's case — useful for un-flipping text someone typed with caps lock half-on. aLtErNaTiNg takes letters in turn, lower-UPPER-lower-UPPER, for the unmistakable look of a playful (or gently mocking) post.

What each one does, exactly

Inverse looks at each letter alone: capitals become small, small letters become capitals, everything else is untouched. Applied twice, it returns your original text exactly. Alternating ignores spaces and punctuation while counting — only letters advance the pattern — and always starts lowercase, which is why “hello world” comes out as hElLo WoRlD: the W is a letter position 6, and it lands on an uppercase step.

Honest note on the mocking-spongebob thing

Alternating case is famous as the “mocking” meme format. It is also genuinely tiring to read in long passages and can read as rude out of context — the tool will happily convert a whole essay, but your audience may not thank you. Keep it to a line or two.

FAQ

Why doesn't alternating start with a capital?

The convention (and the meme) starts lowercase: hElLo, not HeLlO. If you need the opposite phase, run iNVERSE on the alternating result.

Do digits advance the alternating pattern?

No. Only letters count, so “abc123def” alternates across the letters as if the digits were not there.

Is inverse the same as UPPER or lower?

No — those force every letter one way. Inverse preserves the pattern of the original, flipped: mixed case stays mixed, just swapped.
