Case Converter

This case converter rewrites whatever you type into eleven different styles at once — UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, CONSTANT_CASE, kebab-case, dot.case and aLtErNaTiNg cAsE — and updates every one live as you edit. Each result has its own copy button, so you grab the exact style you need in one tap. Your original text in the box is never altered.

The programming styles map to real naming conventions. camelCase and PascalCase are the norm for JavaScript variables and class names; snake_case suits Python and database columns; CONSTANT_CASE is the convention for environment variables and config constants; kebab-case is what URLs, CSS classes and file names expect; and dot.case shows up in property paths and config keys. Title Case and Sentence case are for prose — headings, buttons and email copy — while alternating case is mostly for memes.

Everything runs entirely in your browser with plain JavaScript. Nothing is uploaded, logged or sent to a server, so you can safely paste code, private notes or client copy. Because it is pure string transformation, the output is instant and identical every time — no rate limits and no waiting on a network round-trip.
