FAQ
Common questions
Is my text uploaded anywhere?
No. Conversion happens entirely in your browser.
How accurate is Title Case and Sentence case?
Title Case capitalises each word (optionally keeping short words like "a", "of" and "the" lowercase). Sentence case lowercases everything and capitalises the first letter of each sentence and line. Neither knows about proper nouns, acronyms or brand names such as "iPhone", so review the result.
How are camelCase, snake_case and similar styles split into words?
Words are split at spaces and punctuation, at lower-to-upper changes (helloWorld), at acronyms (XMLHttpRequest becomes XML Http Request) and between letters and digits. Each line is converted separately, so line breaks are kept.
Does it work with accented and non-Latin letters?
Yes for letters that have upper and lower case, such as é, ü or Cyrillic. Scripts without case, such as Chinese or Japanese, are left unchanged by the case styles.
