What case options are available?

Seven options: UPPER CASE, lower case, Title Case, camelCase, snake_case, kebab-case, and CONSTANT_CASE.

How does Title Case work?

Title Case capitalizes the first letter of every word while lowering the rest. For example, 'hello world' becomes 'Hello World'.

How are camelCase and snake_case generated?

The text is first split into words (by spaces, hyphens, or underscores), then joined using the target format. For camelCase, the first word is lowercase and subsequent words are capitalized. For snake_case, all words are lowercase and joined with underscores.
