Delimiters Specify delimiters on which the selected column will be parsed into multiple columns. For example, to parse a column with data of the format “10_5N_1”, specify the underscore (_) to create three new columns with one containing “10”, another containing “5N”, and the other containing “1”. To Specify Delimiters for Parsing: Type the delimiters into the Delimiters text box. Separate multiple delimiters with spaces.
