camelCase to lowercase Converter

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

To convert camelCase to lowercase, 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. Lowercasing is how you normalise text before comparing it — though for user-facing comparisons, locale matters: Turkish dotted and dotless i famously break naive lowercasing.

About converting CAMELCASE to LOWERCASE

camelCase is the convention for variables and functions in JavaScript, Java and C#. Lowercasing is how you normalise text before comparing it — though for user-facing comparisons, locale matters: Turkish dotted and dotless i famously break naive lowercasing. Converting camelCase to lowercase 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.
