Frequently Asked Questions

Is my data secure?
All processing happens directly in your browser using JavaScript. Your data is never sent to any server, stored, or shared. It stays entirely on your device.
What is the difference between Title Case and Sentence case?
Title Case capitalizes the first letter of every word. Sentence case only capitalizes the first letter of the first word (and proper nouns if you add them manually).
Does camelCase conversion handle spaces and underscores?
Yes. The converter treats spaces, underscores, and hyphens as word boundaries when converting to camelCase or PascalCase.
