Alternating Case Converter

Walk every letter upper then lower (or the reverse vibe). Spaces and punctuation stay put — only letters flip for that sarcastic aLtErNaTiNg look.

Letters alternate starting with uppercase by default. Non-letters are skipped so the rhythm stays on A–Z and other alphabetic characters. Pair with Inverse Case when you want to flip whatever caps are already there.

What is alternating case?

Alternating case (sometimes called sarcastic case or mock case) capitalizes every other letter: aLtErNaTiNg. It is a playful transform, not a style-guide headline format.

Does it skip spaces and punctuation?

Yes. Only letters toggle. Spaces, digits, emoji, and punctuation keep their place so the pattern stays readable.

Is this the same as inverse case?

No. Alternating rebuilds a new upper/lower pattern from scratch. Inverse Case flips each letter’s existing case (Hello → hELLO).

Where is alternating case used?

Memes, mock quotes, Discord emphasis, and informal social posts. Avoid it for professional email, docs, or SEO titles.

Does my text leave the browser?

No. The alternating case converter runs in JavaScript on this page. Your paste is not uploaded.
