Frequently asked questions

What is camelCase vs snake_case?

camelCase starts with a lowercase letter and capitalizes the first letter of each subsequent word (`userFirstName`), while snake_case joins lowercase words with underscores (`user_first_name`).

What is kebab-case?

kebab-case joins lowercase words with hyphens (`user-first-name`), commonly used in URLs, CSS class names, and command-line flags.

What is CONSTANT_CASE?

CONSTANT_CASE joins uppercase words with underscores (`MAX_RETRY_COUNT`), standard for global constants in languages like Java, C++, and Python.

Can I convert multiple lines of text at once?

Yes! The converter formats each line or variable identifier independently while preserving line breaks.

Is my code kept private?

Yes. All string manipulation executes in browser memory using JavaScript regular expressions; zero code data is uploaded.
