Frequently asked questions
How do I convert text to lowercase?
Paste the text in the input box and click lowercase. The output updates as you type, and the copy button puts the result on your clipboard.
What is the difference between title case and sentence case?
Title case capitalizes every significant word and leaves short words like a, the, of and in lowercase unless they open or close the line. Sentence case capitalizes only the first word after each period, question mark or exclamation mark.
Does the title case option capitalize small words?
No. It keeps a, an, the, and, but, or, for, nor, on, at, to, from, by, of, in lowercase, except when one of them is the first or last word of the line.
How does camelCase handle an existing identifier?
Each line is split into words on spaces, punctuation and existing case boundaries, so parse_html_value and parseHTMLValue both convert to parseHtmlValue.
