FAQ
Does Korean convert too?+
Korean has no case, so it stays unchanged. Only English parts are converted.
What's the difference between cases?+
camelCase (JS variables), PascalCase (class names), snake_case (Python, DB), kebab-case (URLs, CSS), CONSTANT_CASE (constants).
What rules does English Title Case follow?+
Default Title Case capitalizes every word. For APA/Chicago rules (lowercase short prepositions), use the English Title Case tool.
Can I convert text that's already in another case?+
Yes — any case can convert to any other. 'helloWorld' → 'hello_world' → 'HELLO-WORLD' all work.
Is Sentence case available?+
Yes. Sentence form (first letter capital, rest lowercase) is also an option.
