What is camelCase?

camelCase keeps the first letter lowercase, then capitalises the first letter of each subsequent word, removing spaces and separators. "user login count" becomes "userLoginCount".

When should I use camelCase?

Use camelCase for variable names and function names in JavaScript, TypeScript, Java, Swift, Dart, and most other languages. It is also used for JSON keys in most APIs.

What is the difference between camelCase and snake_case?

camelCase joins words by capitalising (userLoginCount). snake_case uses underscores (user_login_count). camelCase is standard in JS/Java/Swift; snake_case is standard in Python, PHP variables, and SQL columns.

Does it handle acronyms correctly?

Acronyms in input (like "XML" or "URL") are treated as single words. "parse XML response" becomes "parseXmlResponse" in camelCase — each letter of the acronym is not capitalised individually.

Can I convert multiple lines at once?

Yes — each line is converted independently. Paste a list of identifiers one per line and every line gets converted. This is ideal for bulk renaming of variables or database columns.

Is my text private?

Yes. All conversion runs locally in your browser. Nothing is sent to any server.
