Frequently asked questions
What is the difference between title case and sentence case?
Title Case capitalizes the first letter of every word, the style of headlines. Sentence case capitalizes only the first word of each sentence, the style of normal prose.
How does camelCase conversion decide where words start?
Spaces, hyphens and underscores are treated as word boundaries, then the words are joined with each one after the first capitalized. so 'user login count' becomes userLoginCount.
Can I fix a paragraph I typed with caps lock on?
Yes, paste it and click Sentence case. Everything drops to lowercase except the first letter of each sentence, which saves retyping the whole thing.
