What's the difference between camelCase and PascalCase?

camelCase starts the first word in lowercase and capitalizes the first letter of subsequent words (e.g., myVariableName). PascalCase capitalizes the first letter of every word (e.g., MyVariableName). Typically, camelCase is used for variables/functions, while PascalCase is used for classes/components.

Where are snake_case and kebab-case commonly used?

snake_case is commonly used in Python, Ruby, and database column names. kebab-case is commonly used in URL slugs, CSS class names, HTML attributes, and file names.

When should I use CONSTANT_CASE?

CONSTANT_CASE (SCREAMING_SNAKE_CASE) is used to represent constant values. In most programming languages, this convention is applied to immutable values, environment variables, configuration keys, etc.

Does it automatically detect the input text case?

Yes, it analyzes the delimiters (spaces, hyphens, underscores) and capitalization patterns of the input text to automatically detect the current case and accurately convert it to other cases.

Can I convert text with multiple words?

Yes, the tool automatically separates words from space-separated text, hyphen-connected text, or text that already has a case convention applied.
