Frequently Asked Questions
What case formats does the converter support?
- The tool supports 11 formats: UPPER CASE, lower case, Title Case, Sentence case, camelCase, PascalCase, snake_case, SCREAMING_SNAKE_CASE, kebab-case, UPPER-KEBAB-CASE, and dot.case.
Can it convert camelCase or snake_case input back to words?
- Yes. The tokeniser automatically splits camelCase, PascalCase, snake_case, kebab-case, and dot.case inputs into individual words before converting, so mixed inputs are handled correctly.
Does my text get sent to a server?
- No. All conversion logic runs entirely in your browser using JavaScript. Your text is never transmitted to any server.
What is the difference between camelCase and PascalCase?
- In camelCase the first word is lowercase and subsequent words are capitalised (e.g. helloWorld). In PascalCase (also called UpperCamelCase) every word including the first starts with a capital letter (e.g. HelloWorld). PascalCase is common for class names; camelCase for variables and function names.
