⭐ Supported Case Formats Explained
Capitalized Case capitalizes the first letter of every single word regardless of what the word is. Title Case is smarter—it capitalizes main words but leaves minor words (like “a”, “an”, “the”, “and”, “but”, “or”, “for”, “in”, “on”) in lowercase, unless they are the first word of the sentence. This is the standard format used for book titles, article headlines, and movie names.
Our tool works instantly in the browser. If it doesn’t seem to work, make sure you have text in the box and you’ve clicked a formatting button. Sentence case relies on punctuation (periods, exclamation marks, question marks) to know where a new sentence begins, so ensure your text has proper punctuation.

These are naming conventions used by software developers. camelCase capitalizes the first letter of each word except the first, with no spaces. snake_case replaces spaces with underscores. kebab-case replaces spaces with hyphens. These are essential for writing clean, working code in languages like JavaScript, Python, and HTML/CSS.
