Use the Recode option if you need to recode similar values within multiple columns in the same way. After you click Recode, the values that appear are generated from the union of all of the selected columns. For example, suppose that you have two columns with user responses. One column contains the values Agree and Disagree. The other column contains the values Agree, Disagree, Unsure, and Strongly Disagree. You want to simplify all of the values in both columns to be A, D, U, and SD.
Note: If you want to recode values only in a single column, you can also use the Cols > Recode option. See Recode Data in a Column.
