Change text case on your Mac

Case Converter switches text between twelve styles: UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, CONSTANT_CASE, kebab-case, dot.case, alternating and inverse. Every style previews your own text, so you can see the result before you pick one. Title Case keeps short words like of and the lowercase, and leaves names like iPhone and NASA as they are. The programming styles split words correctly, so getHTTPResponse becomes get_http_response.

Questions about Case Converter

How do I convert text to title case on a Mac?

Paste it into Case Converter and choose Title Case. Small words like a, of and the stay lowercase unless they start or end the title or follow a colon, and words with their own capitals, like iPhone, are kept.

Can it convert between camelCase and snake_case?

Yes. It splits words at capitals, numbers, spaces, dashes and underscores, including acronyms, then joins them in the style you choose. Each line is converted on its own, so you can convert a list of names at once.

Is it free, and is my text uploaded?

Toolbox is a paid app, and one purchase includes every tool, with no subscription or account. Text is converted on your Mac and never sent anywhere.
