Frequently asked questions
What is the difference between Title Case and Capitalize Each Word?
Title Case leaves short words like "a" and "of" lowercase. Capitalize Each Word makes the first letter of every word uppercase.
Can it convert variable names?
Yes. camelCase, PascalCase, snake_case, kebab-case and CONSTANT_CASE split words from any existing style, so "userFirstName" becomes "user_first_name".
Does it work with accents and non-English letters?
Yes. The converter is Unicode aware, so letters such as é, ü and ñ change case correctly.
