Frequently Asked Questions
Is my text sent to any server?
No. All case conversion happens entirely in your browser using JavaScript. Your text never leaves your device.
What is camelCase?
camelCase is a naming convention where the first word is lowercase and each subsequent word starts with an uppercase letter, e.g. myVariableName. It is widely used in JavaScript and Java.
What is the difference between camelCase and PascalCase?
In camelCase the first letter is lowercase (myVariable), while in PascalCase every word starts with an uppercase letter (MyVariable). PascalCase is common in C# and TypeScript class names.
Can I convert multiple lines at once?
Yes. Paste or type multiple lines of text and the converter will process every line simultaneously.
