The five case styles, explained
UPPERCASE
Every letter capitalized. Good for labels and warnings — hard to read in long passages.
lowercase
Every letter small. Handy for normalizing usernames, tags, and code-like text.
Title Case
The first letter of each word is capitalized — the style of headlines and book titles.
Sentence case
Only the first letter of each sentence is capitalized, like normal writing.
aLtErNaTiNg case
Letters alternate between lower and upper case. Mostly for fun and memes.
Note: converters follow simple rules. Names, acronyms (like NASA), and brand spellings may need a quick manual touch-up afterwards.
