Frequently Asked Questions

How does Title Case work?▼

Every word is capitalised except short words such as a, an, the, and, of, in and to (unless they start or end the title or follow a colon). Acronyms like NASA and brand spellings like iPhone are left as they are.

What is the difference between Title Case and Capitalized Case?▼

Capitalized Case capitalises every word, including small words like “of” and “the”.

Can it split existing camelCase?▼

Yes. “XMLHttpRequest userId” becomes xml_http_request_user_id in snake_case. Each line is converted separately.

Does it work with accents?▼

Yes, accented and non-Latin letters are converted correctly.
