Nine styles: camelCase (helloWorld), PascalCase (HelloWorld), snake_case (hello_world), kebab-case (hello-world), CONSTANT_CASE (HELLO_WORLD), dot.case (hello.world), path/case (hello/world), Header_Case (Hello_World), and sentence case (Hello world).
How does it detect word boundaries?
It recognizes spaces, hyphens, underscores, and camelCase capitalization as word boundaries. For example, 'helloWorld' correctly splits into 'hello' and 'World'.
Can I convert multiple lines?

Does it support non-ASCII characters?

Is my text sent to a server?
No. All case conversion is done locally in the browser using JavaScript string manipulation. Your text never leaves your device.
