Frequently asked questions
What is the difference between camelCase and PascalCase?
camelCase starts with a lowercase letter, while PascalCase capitalizes the first word.
What is kebab-case?
Words joined with hyphens, common in URLs and CSS class names.
Does it handle Chinese?
Case modes leave Chinese characters unchanged, and word-based modes keep CJK tokens together.
Can I convert code identifiers?
Yes. camelCase, snake_case and kebab-case split existing camelCase identifiers correctly.
Is my text uploaded?
No. Everything runs locally in your browser.
