FAQ

What is camelCase?

camelCase writes compound words with no spaces, where each word after the first starts with an uppercase letter. Example: myVariableName. It is commonly used for variable and function names in JavaScript, Java, and Swift.

What is the difference between snake_case and kebab-case?

snake_case separates words with underscores (my_variable_name) and is common in Python and Ruby. kebab-case separates words with hyphens (my-variable-name) and is common in CSS class names and URL slugs.

What is PascalCase used for?

PascalCase (also called UpperCamelCase) capitalizes the first letter of every word with no separators. Example: MyClassName. It is the standard for class names and component names in most programming languages.

Can I convert multiple lines at once?

Yes. The case converter processes your entire input, converting all text to the selected case format.
