Text Case Converter
Convert text between common writing and identifier case styles.
Paste text and convert it into everyday writing styles or code-friendly identifier cases. The conversion runs locally in your browser and does not upload your text.
How it works
Output case can generate one selected conversion or every supported conversion at once. Writing cases preserve punctuation and can keep line breaks. Identifier cases split words, normalize whitespace, and join with the selected casing rules.
Drop punctuation instead of treating it as word separators changes how identifier cases handle punctuation. Leave it off when punctuation should separate words, such as alpha.beta becoming alpha_beta. Turn it on when punctuation should be removed before joining, such as alpha.beta becoming alphabeta.
Title case and sentence case are simple formatting helpers, not grammar-aware editorial rules. Case conversion can vary for locale-sensitive text, acronyms, names, and symbols, so review output that depends on language-specific casing.
Input stays in the browser. Do not paste secrets into any web tool unless you are comfortable with the device and page context you are using.
