Case Converter

How it works

Different contexts demand different cases, and retyping is error-prone. This converter generates nine forms at once. UPPER CASE and lower case transform every letter. Title Case capitalizes the first letter of each word, the style used for headlines and book titles. Sentence case capitalizes the first letter after each sentence-ending punctuation mark and lowercases the rest. The programming cases treat your text as a sequence of words: camelCase removes spaces and capitalizes every word except the first (standard for JavaScript variables), PascalCase capitalizes the first word as well (standard for class names), snake_case joins words with underscores (Python and database columns), kebab-case joins with hyphens (URLs and CSS class names), and CONSTANT_CASE uses uppercase with underscores (constants and environment variables). Numbers stay attached to their word, and extra punctuation is treated as a word separator in the programming cases. Because the conversions are lossy in small ways (original capitalization inside words is discarded), keep your source text if you need the exact original later. Like every tool in this hub, the conversion happens locally in your browser.
