This converter rewrites snake_case identifiers as camelCase. For example, my_variable_name becomes myVariableName. It splits on case boundaries and separators, so mixed input still converts cleanly. Paste one identifier or a whole list.
Everything runs in your browser. No cost, no signup, no tracking.
Frequently asked questions
Does it handle acronyms and numbers?
Yes. Runs of capitals and trailing numbers are treated as word boundaries, so identifiers like parseHTML5 split sensibly before converting to camelCase.
