Frequently asked questions

Which cases can I convert to?
camelCase, PascalCase, snake_case, CONSTANT_CASE, kebab-case, Train-Case, Capital Case, Sentence case, dot.case, path/case, plus flattened lower case and UPPER CASE. Every format is shown at once, so you can copy whichever you need.
Does it handle camelCase, acronyms, and mixed input?
Yes. The converter tokenizes intelligently, so helloWorld, HELLO_WORLD, and "hello-world" all split into the same words. Acronyms like XMLHttpRequest become xml-http-request or xmlHttpRequest correctly.
Can I convert a whole list at once?
Yes. Turn on "Convert each line separately" and every line is tokenized on its own — paste a column of names or keys and get a converted list back, blank lines preserved.
What's the difference between camelCase and PascalCase?
Both remove separators and capitalize word boundaries, but camelCase keeps the first letter lowercase (myVariableName) while PascalCase capitalizes it too (MyVariableName). PascalCase is common for class and type names; camelCase for variables and functions.
Is my text uploaded anywhere?
No. All conversion happens in your browser with JavaScript — nothing is uploaded, logged, or stored. It's free with no sign-up; a single unobtrusive ad slot covers hosting.
