About Case Converter

Retyping text just to change its capitalisation is one of those small tasks that eats a surprising amount of time. A heading arrives in ALL CAPS, a spreadsheet column needs to become database field names, or a list of labels has to match a naming convention. This converter does all of it in one click.

The nine supported cases split cleanly into two groups. Sentence case, Title Case, UPPERCASE and lowercase are for prose — headlines, labels, product names. camelCase, PascalCase, snake_case, kebab-case and CONSTANT_CASE are for code, where each language and framework has its own convention for variables, files, CSS classes and environment variables.

Because word boundaries are detected rather than assumed, you can convert between any two cases without an intermediate step. Paste kebab-case and get CONSTANT_CASE; paste a Title Case heading and get a clean URL-ready form. The text stays in your browser throughout.

Frequently asked questions

Which cases are supported?+

UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case and CONSTANT_CASE — the nine that cover writing and code.

Will it handle text that is already camelCase?+

Yes. Word boundaries are detected from spaces, punctuation and capital-letter humps, so "myXMLFile" and "my-xml-file" both convert to the same result in any target case.

Does Title Case follow a style guide?+

It capitalises the first letter of every word, which matches how most CMS fields and headline generators behave. Strict AP or Chicago style leaves short prepositions lowercase, so give headlines a read before publishing.

Can I convert a whole document?+

Yes. Paste as much as you like — the conversion is instant because it runs locally rather than on a server.

What is the difference between camelCase and PascalCase?+

Both remove the spaces; camelCase leaves the first word lowercase (userName) while PascalCase capitalises it (UserName). JavaScript variables usually use camelCase, class names use PascalCase.

Is my text private?+

Completely. The conversion happens in your browser and nothing is uploaded, stored or logged.
