Frequently asked questions
What's the difference between camelCase and PascalCase?
camelCase starts with a lowercase letter (myVariableName); this tool produces camelCase, which is the convention most JavaScript and Java code uses for variable and function names.
Does Sentence case only capitalize the first word?
It capitalizes the first letter after any sentence-ending punctuation (., !, ?) as well as the very start of the text, so multi-sentence input is handled correctly.
Is my text sent to a server to convert the case?
No — all conversions run with plain JavaScript in your browser. Nothing you type here is uploaded anywhere.
