Frequently asked questions

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 letter of each sentence, leaving the rest lowercase.

Does it handle camelCase input correctly?

Yes. Existing camelCase and PascalCase words are split on the capital letters before being re-joined in the target case, so "userName" becomes "user_name" rather than "username".

Why show all the cases at once?

Because most people are comparing options rather than committing to one in advance. Seeing kebab-case next to snake_case next to CONSTANT_CASE makes the choice obvious without repeatedly changing a dropdown.
