If the trim option is enabled then any whitespace in the beginning and in the end of each unquoted field will be trimmed. For example with configuration above, a value of A, B will result in field field2 having value {nbsp}B (with space at the beginning). If trim is enabled A, B will result in field field2 having value B (no whitespace). Quoted fields will be left untouched.
