Examples

The same phrase in every case

Input
hello world example
Result
UPPERCASE: HELLO WORLD EXAMPLE
Title Case: Hello World Example
camelCase: helloWorldExample
snake_case: hello_world_example
kebab-case: hello-world-example

One phrase shown across the common cases. Title Case capitalizes each word; the developer cases (camel, snake, kebab) join the words with different conventions used in code and URLs.

Cleaning up copied text

Input
tHiS wAs TyPeD wEiRd
Result
Sentence case: This was typed weird

Sentence case capitalizes only the first letter of each sentence — handy for normalizing text that was pasted with random capitalization.
