Frequently asked questions
When would I use camelCase vs. snake_case vs. kebab-case?
camelCase and PascalCase are common variable/class naming conventions in JavaScript, Java, and C#. snake_case is standard in Python and most database column names. kebab-case is common in URLs, CSS class names, and file names. Pick whichever matches the convention of the codebase or platform you're working in.
What's the difference between Title Case and Sentence case?
Title Case capitalizes the first letter of most words (used for headlines and titles). Sentence case capitalizes only the first letter of the whole text, like normal prose — useful for cleaning up text that was accidentally typed in all caps.
Does this handle punctuation and numbers correctly?
Yes — camelCase, PascalCase, snake_case, and kebab-case conversions split on spaces and punctuation to identify word boundaries, and numbers are preserved as part of the adjacent word.
Is my text sent anywhere?
No — every conversion runs directly in your browser using plain JavaScript string methods. Nothing is sent to a server.
