Frequently Asked Questions
camelCase starts with a lowercase letter with subsequent words capitalized (myVariableName). PascalCase capitalizes every word including the first (MyVariableName). camelCase is common in JavaScript/Java, while PascalCase is used for class names and C#.
snake_case (words_separated_by_underscores) is standard in Python and database column names. kebab-case (words-separated-by-dashes) is used for URLs, CSS classes, and file names since dashes are URL-safe.
Sentence case capitalizes only the first letter of the text (Like a regular sentence). Title Case capitalizes the first letter of each word (Like A Book Title). Use Sentence case for casual text and Title Case for headlines.
The behavior depends on the case type. For programming cases (camelCase, snake_case), special characters and spaces are typically removed. For text cases (Title, Sentence), punctuation is preserved.
Yes! The tool processes multi-line text, converting each line according to the selected case type. This is useful for batch-converting variable names or list items.
