Sentence case to CONSTANT_CASE Converter

Convert Sentence case text to CONSTANT_CASE — one line or a whole list at once.

To convert Sentence case to CONSTANT_CASE, paste your text above and the result updates as you type. User account id becomes USER_ACCOUNT_ID. Word boundaries are detected from the existing casing, so an identifier does not need separators to be split correctly. CONSTANT_CASE marks compile-time constants and environment variables across nearly every language.

About converting SENTENCECASE to CONSTANTCASE

Sentence case is the modern default for interface labels and button text; it reads faster than Title Case and is far easier to keep consistent. CONSTANT_CASE marks compile-time constants and environment variables across nearly every language. Converting Sentence case to CONSTANT_CASE turns User account id into USER_ACCOUNT_ID; acronyms are the awkward case in every direction, since "userID" and "userId" split differently and only one of them round-trips.
