Frequently asked questions

What is the difference between Title Case and Capitalized Case?

Capitalized Case capitalises the first letter of every word. Title Case follows headline style: short articles, conjunctions and prepositions such as “a”, “and” and “of” stay lowercase unless they are the first or last word.

Can it convert camelCase to snake_case?

Yes. The converter splits words at spaces, punctuation and lower-to-upper case changes, so “parseHTTPResponse” becomes parse_http_response in snake_case or parse-http-response in kebab-case. Each line is converted separately.

Does sentence case keep names capitalised?

No. Sentence case lowercases everything except the first letter of each sentence and the word “I”, so names and acronyms need to be re-capitalised by hand afterwards.
