camelCase to CONSTANT_CASE Converter

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

To convert camelCase to CONSTANT_CASE, paste your text above and the result updates as you type. userAccountId 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 CAMELCASE to CONSTANTCASE

camelCase is the convention for variables and functions in JavaScript, Java and C#. CONSTANT_CASE marks compile-time constants and environment variables across nearly every language. Converting camelCase to CONSTANT_CASE turns userAccountId 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.
