Does it handle existing camelCase or snake_case?

Yes. The converter splits camelCase, PascalCase, snake_case and kebab-case input into words before re-casing, so identifiers convert cleanly.

What is the difference between Title Case and Sentence case?

Title Case capitalises the first letter of every word; Sentence case capitalises only the first word and lowercases the rest.

Smart word splitting

The converter understands existing camelCase, snake_case and kebab-case input, so it can re-case identifiers correctly — turning getUserID into get_user_id or GET-USER-ID cleanly.

Built for developers and writers
