You can convert text to uppercase, lowercase, sentence case, title-style capitals, slug, camelCase, or snake_case.

Uppercase and lowercase quickly standardise text. Sentence case and capitals help reformat headings or labels.
Slug, camelCase, and snake_case are useful for filenames, identifiers, CSS classes, variables, and technical content.
