How does camelCase conversion work?

The tool splits the input into words by detecting spaces, underscores, hyphens, dots, and camelCase boundaries, then joins them in the target format.

What is the difference between camelCase and PascalCase?

camelCase starts with a lowercase letter (e.g. helloWorld), while PascalCase starts with an uppercase letter (e.g. HelloWorld). Both join words without separators.

What is CONSTANT_CASE?

CONSTANT_CASE (also called SCREAMING_SNAKE_CASE) uses all uppercase letters with underscores between words. It is commonly used for constants and environment variables.

Is my text stored anywhere?

No. All conversion happens in your browser in real time. Your text is never sent to any server.

camelCase writes compound words with no spaces, with each word after the first starting with a capital letter (e.g., myVariableName). It is commonly used in JavaScript and Java.

snake_case writes compound words with underscores between words, all in lowercase (e.g., my_variable_name). It is commonly used in Python and database column names.

Title Case capitalizes the first letter of each major word (e.g., The Quick Brown Fox). It is used for headings, titles, and proper nouns.
