Text case conversion is a daily task for developers, writers, and content managers. This tool converts any text between ten common case formats instantly — no copy-paste-retype cycle needed. Paste your text, click the target format, and copy the result to your clipboard. Everything runs in your browser with no data sent anywhere.
Programming Case Formats
Coding conventions vary by language and framework. JavaScript and TypeScript use camelCase for variables and PascalCase for classes and components. Python uses snake_case for variables and functions. URLs, CSS class names, and command-line arguments use kebab-case. Configuration keys and package names sometimes use dot.case. Having a quick converter eliminates the mental overhead of reformatting between standards when moving text between systems, renaming variables, or writing documentation.
Writing and Content Case Formats
Title Case capitalizes the first letter of every word — the standard for headlines, headings, and proper nouns in English-language publishing. Sentence case capitalizes only the first word of each sentence, which is the default for body text and most UI strings. UPPER CASE is used for acronyms, emphasis, and certain legal and regulatory contexts. Toggle Case flips the case of every character, a quick way to undo an accidental Caps Lock or create stylized text for creative use.
