FAQ
When should I use camelCase versus snake_case?
JavaScript, Java and C# conventionally use camelCase for variables; Python, Ruby and database columns use snake_case; CSS class names and URL slugs use kebab-case. Just follow the convention of the language you are in.
Does Title Case handle Chinese?
Chinese has no case, so it is preserved as-is. English words are split on spaces, underscores and hyphens and each one is capitalised.
Why is my camelCase output a single word?
Conversion splits on spaces, underscores and hyphens. If your text has no separators it counts as one word — add separators first.
Can I convert a whole column of text?
Yes. Paste multi-line text into the box; the same rules apply to the entire block, and you can copy the result out in one go.
