Where this format is used
Alternating capitals are used online to give a line a mocking or sarcastic tone, usually when quoting someone back to themselves. It also turns up in captions and usernames where the look matters more than the reading.
There is no shortcut for this one
Word and Excel have no built in alternating case, and doing it by hand means retyping every second letter. That is the main reason to use a converter for this format rather than the others.
Common questions
How do I write in alternating caps?
Paste your text above and choose aLtErNaTe. Every second letter becomes a capital, and spaces and punctuation are left alone.
Does the pattern start with a small or a capital letter?
It starts lowercase, so the first letter is small and the second is a capital. The pattern follows the letters only, so punctuation does not break the rhythm.
Is the alternating case converter free?
Yes. It is free to use online, works on any browser, and nothing you paste is uploaded.
