FAQ

How does it find the words?

It splits the input at spaces, hyphens, underscores and at every change from a lowercase to an uppercase letter (parseEmail becomes parse Email), then rebuilds the words in each style.

What are the limits?

Runs of capitals are not split, so XMLHttpRequest becomes xmlhttpRequest. Digits stay attached to their word, and dots or other punctuation stay inside words (foo.bar is one word).

Is my text uploaded?

No. The conversion runs in your browser as you type and nothing is sent anywhere.
