Case Converter

Converts a phrase into camelCase, PascalCase, snake_case, kebab-case and 5 more styles at once.

What this tool does

Enter text in any style — a space-separated phrase, snake_case, camelCase, PascalCase, or a mix — and the tool detects the word boundaries and outputs all 9 common naming styles at once: camelCase, PascalCase, snake_case, SCREAMING_SNAKE_CASE, kebab-case, dot.case, Title Case, lowercase, and UPPERCASE. No more retyping words letter by letter.

Typical use cases

Switching between language conventions: camelCase for JavaScript and Java variables, snake_case for Python and database columns, PascalCase for classes, kebab-case for URLs and CSS classes, SCREAMING_SNAKE_CASE for environment variables. When an API returns user_name and your frontend expects userName, this tool shows every variant in one shot.

Caveats

Case conversion only applies to Latin-letter words. Acronyms are a gray area: HTTPResponse splits into http_response cleanly, but fused all-caps forms like XMLHTTP cannot be segmented reliably — separate those words manually first. And the team rule worth repeating: which style you pick matters less than sticking to it project-wide.
