Frequently Asked Questions

Does Title Case follow specific grammar rules?

This tool capitalizes every word for simplicity. Strict AP/Chicago style rules exclude articles (a, an, the), short prepositions (of, in, on), and coordinating conjunctions (and, but, or) unless they are the first or last word.

How does camelCase handle acronyms?

This tool treats acronyms as regular words — e.g., "XML parser" becomes "xmlParser". Some style guides prefer "XMLParser" — adjust manually if needed.
