How conversion works
Paste text, choose a style, and select Convert text. Changing styles always starts from your original text. Uppercase and lowercase keep spacing and punctuation. Sentence case capitalizes at sentence starts and line breaks. Title Case uses a simple English small-word rule; it does not certify a particular editorial style.
Sentence, title and word capitalization first lowercase the text, so proper names and acronyms can change. Review the result before using it.
For code identifiers
camelCase, PascalCase, snake_case, kebab-case and CONSTANT_CASE split words at spaces, punctuation and letter-case boundaries. These identifier styles remove punctuation and normalize spacing. Each input line is converted independently; blank lines remain.
