About Case Converter

Case Converter changes the letter case of any text with a single click. Beyond the basics — UPPERCASE, lowercase, Title Case and Sentence case — it also covers the identifier-style cases developers reach for constantly: camelCase, PascalCase, snake_case, kebab-case and CONSTANT_CASE, plus two playful ones, aLtErNaTiNg cAsE and InVeRsE CaSe. Paste a heading that needs Title Case for a document, a variable name you need in snake_case for Python or camelCase for JavaScript, or a wall of text a caps-lock key left shouting — pick a case and the result updates instantly. Everything runs locally in your browser: your text is never uploaded to a server.

FAQ

Does this tool upload my text anywhere?: No. Your text is converted entirely in your browser and never sent to a server.
What's the difference between camelCase, PascalCase, snake_case and kebab-case?: They're all ways of writing a multi-word identifier without spaces: camelCase starts lowercase (helloWorld), PascalCase capitalizes every word (HelloWorld), snake_case joins words with underscores (hello_world), and kebab-case joins them with hyphens (hello-world).
Does converting to camelCase or snake_case work on text with spaces?: Yes — spaces, punctuation and even existing hyphens or underscores are all treated as word boundaries, so "Hello, World!" converts to "helloWorld" in camelCase just like "hello world" would.
What does Sentence case do?: It lowercases the whole text, then capitalizes the first letter of the text and the first letter after every '.', '!' or '?'.
Is there a limit on how much text I can convert?: No — convert a single word or an entire document, with no limits, sign-up or hidden fees.
