Common questions
Does it handle multi-word variable names correctly?
Yes - it splits on spaces, hyphens, underscores, and camelCase word boundaries before reformatting into your chosen case.
Can I convert code identifiers, not just sentences?
Yes - camelCase, PascalCase, snake_case, and kebab-case are all meant for variable and file naming conventions.
Is my text uploaded anywhere?
No - all case conversion runs locally in your browser.
Does it handle Sentence case for regular writing?
Yes - Sentence case capitalizes only the first letter of each sentence, suitable for headlines and body copy.
