FAQ

Does camelCase handle existing mixed case?

Yes. The converter splits on spaces, hyphens, underscores, and existing camelCase boundaries before rebuilding in the target format.

What is kebab-case used for?

URLs, HTML class names, and CSS custom properties typically use kebab-case. It's lowercase and human-readable.

What is snake_case used for?

Python variable and function names, database column names, and file names in many languages conventionally use snake_case.
