Frequently Asked Questions

Does Title Case capitalize prepositions and conjunctions?

Our AP/Chicago-style Title Case rules automatically keep short prepositions and articles (like "and", "the", "in", "of", "to") in lowercase unless they are the first or last word of a title.

What programming naming conventions can I convert between?

You can convert between camelCase (JavaScript), PascalCase (TypeScript/C#), snake_case (Python), kebab-case (CSS/URLs), and CONSTANT_CASE.

Does the case converter support accented characters and non-Latin scripts?

Yes! Full Unicode case mapping handles accented characters (e.g., é, ö, ñ, ç) and multi-byte scripts correctly.
