Case Converter

Switch text between UPPER, lower, Title, Sentence, camelCase and snake_case instantly.

Case Converter flips any block of text between every casing style writers and developers reach for: UPPERCASE for headlines, lowercase for casual copy, Title Case for blog posts, Sentence case for body paragraphs, camelCase for JavaScript identifiers, PascalCase for class names, snake_case for Python variables, kebab-case for URLs and CSS classes, and CONSTANT_CASE for environment variables. It is the kind of tool you do not realize you need until you are reformatting a list of fifty product names, cleaning up a CSV column of customer emails, normalizing a list of database keys, or fixing a copy-pasted heading that came in screaming. The conversion is instant and runs entirely in your browser, so even if your text is a list of internal SKUs, draft press release copy, or a user export, nothing leaves your device. Writers love it for cleaning up dictation output that always comes back over-capitalized. Developers love it for converting JSON keys between API conventions without writing a one-off script. Marketers love it for matching their brand style guide across product names, ad headlines, and meta titles. Designers love it for pasting client copy and getting it formatted to spec without manual editing. The tool handles long documents, preserves punctuation correctly, and offers a one-click copy button so you can paste the result back wherever you grabbed the original from.
