How to use this calculator
Paste or type text into the box, then click a case button — UPPER CASE, lower case, Title Case, Sentence case, camelCase, PascalCase, snake_case, or kebab-case. The output updates live as you type. Click “Copy result” to put it on your clipboard.
How it works
Each style rewrites word boundaries and letter casing: for example, “hello world” becomes “Hello World” in Title Case, “helloWorld” in camelCase, and “hello_world” in snake_case. Line breaks are preserved. Nothing is sent anywhere — all conversion runs locally in your browser.
