Frequently Asked Questions
When should I use camelCase vs snake_case?
JavaScript, Java, and TypeScript conventionally use camelCase for variables and PascalCase for classes. Python and Ruby prefer snake_case. Database columns often use snake_case regardless of app language.
What is kebab-case used for?
kebab-case appears in URL slugs, HTML attributes, CSS class names, and CLI flags â anywhere hyphens are easier to read than underscores.
Can I convert existing camelCase variable names?
Yes. The tool detects camelCase boundaries automatically, so fetchUserProfile converts to fetch_user_profile and fetch-user-profile.
Is my text sent to a server?
No. Conversions run entirely in your browser.
Does Title Case capitalize every word?
Yes â each word gets an initial capital letter. For sentence-style titles with small words lowercase, manual editing may still be needed.
