Unless you can guarantee that the CSV you are dealing with is absolutely free of fields with embedded newlines, CSV parsing cannot be threaded or parsed in parallel. The OP only deals with fields 7 and 31, which are unlikely to contain new-lines, but we have no idea what the other fields may hold. Enjoy, Have FUN! H.Merijn
