What is a case converter?
A case converter changes the capitalization of text without changing its words. It is useful for cleaning pasted text, preparing headings, and making letter-case changes quickly.
Common case options
UPPERCASE makes every letter capital. lowercase makes every letter small. Sentence case capitalizes the first alphabetic character and the first character after sentence-ending punctuation. Title Case and Capitalized Case capitalize the first letter of each word. Inverse case swaps uppercase and lowercase letters. Alternating case alternates alphabetic characters while ignoring spaces and punctuation.
Examples
hello world. this is a test! becomes Hello world. This is a test! in Sentence case, HELLO WORLD in UPPERCASE, and Hello World in Title Case or Capitalized Case.
