About Case Converter
Case Converter instantly transforms your text between eight common case formats. Whether you need UPPERCASE for constants, camelCase for JavaScript variables, snake_case for Python functions, or kebab-case for CSS class names, this tool handles the conversion in real time as you type.
Typical uses include normalizing API field names when switching between language conventions, converting a headline to title case before publishing, or transforming a CSV column of mixed-case labels into a consistent format. Sentence case is especially useful for fixing text that was accidentally typed in all caps.
All conversions happen locally in your browser — no text is sent to any server.
