About Case Converter

Case Converter switches any piece of text between eight common casing styles: UPPERCASE, lowercase, Title Case, Sentence case, and the four code-identifier styles — camelCase, PascalCase, snake_case, and kebab-case. It's useful for cleaning up pasted text, formatting headlines, or turning a phrase into a variable name or URL slug. Everything runs locally in your browser as you type; nothing you paste is ever sent to a server.

What it does

FAQ

How does the converter detect word boundaries for camelCase or snake_case?

It splits on spaces, hyphens, underscores, and existing camelCase boundaries (a lowercase letter followed by an uppercase letter). This means you can convert already-formatted text — e.g. a snake_case variable name — into any other style, not just plain sentences.

What's the difference between camelCase and PascalCase?

Both join words with no spaces or separators. camelCase keeps the first word lowercase (myVariableName); PascalCase capitalizes every word including the first (MyVariableName).

Does this tool send my text anywhere?

No. All conversion happens locally in your browser as you type. Your text is never uploaded, logged, or stored.
