camelCase to UPPERCASE Converter

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

To convert camelCase to UPPERCASE, 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. Full uppercase is a display choice, not a naming convention. Set it in CSS with text-transform rather than in the data, so the original stays searchable.

About converting CAMELCASE to UPPERCASE

camelCase is the convention for variables and functions in JavaScript, Java and C#. Full uppercase is a display choice, not a naming convention. Set it in CSS with text-transform rather than in the data, so the original stays searchable. Converting camelCase to UPPERCASE 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.
