Yes. The converter recognizes word boundaries in camelCase, PascalCase, snake_case, and kebab-case inputs, so you can convert between any of the 8 styles, not just from plain text.

Title Case keeps spaces between words (Hello World), commonly used for headings. PascalCase removes spaces and capitalizes each word (HelloWorld), commonly used for class names and components.

No. Conversion happens entirely in your browser using plain string operations — nothing is uploaded or stored.
