Frequently asked questions
What is Title Case?
Every major word starts with a capital letter – common for headlines. Our tool capitalises the first letter of every word.
What is camelCase vs snake_case?
Programming naming styles: camelCase joins words and capitalises each after the first (totalPrice); snake_case joins words with underscores (total_price).
Does it work with umlauts and other languages?
Yes, it uses your browser's Unicode-aware case rules, so ä, ß, é or Cyrillic letters are handled.
