Frequently asked questions

Which case formats are supported?: Nine formats: UPPER, lower, Title, camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, and Sentence case.
How are words detected in camelCase or PascalCase?: The tool splits on spaces, underscores, hyphens, and uppercase letter boundaries, so mixed input like hello_worldFoo is handled correctly.
