How it works
Title Case capitalises the first letter of each word but keeps short words such as “and”, “of” and “the” in lowercase unless they start the title, following common English style guides. Sentence case lowercases everything, then capitalises the first letter of each sentence and the pronoun “I”.
Programming cases (camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE) split the text into words at spaces, punctuation and existing case boundaries, so “userIDNumber” and “user id number” both become “user_id_number”. Each line is converted separately, so you can convert a whole list at once.
Examples
- Caps Lock accident
- “tHE QUICK BROWN FOX” → Sentence case → “The quick brown fox”.
- Variable names
- “Order total amount” → camelCase “orderTotalAmount”, snake_case “order_total_amount”, kebab-case “order-total-amount”.

Frequently asked questions
Does it work with accented letters?
Yes. Conversion uses Unicode-aware case mapping, so “élève” becomes “ÉLÈVE” and “straße” is handled correctly.
Which Title Case rules are used?
A simple, widely used rule: capitalise every word except short articles, conjunctions and prepositions (a, an, the, and, or, of, in, on, to…) unless they are the first word.
