Convert Labels to Codes and Codes to Labels

Suppose that you have a column of strings such as “dissatisfied”, “somewhat dissatisfied”, and “somewhat satisfied”, and “satisfied”. You can recode the values to “1”, “2”, “3”, and “4”. The original strings are placed in the Value Labels column property for that column. If the column has a List Check property, the property is removed. The column data type is changed to 1-byte Integer. Converting a column of strings to short numeric codes saves memory and can speed up processing.

You can also convert a numeric column of codes to labels. The column must have value labels. The column data type is changed to Character, and the Value Label column property is removed. This is, in effect, the opposite of converting labels to codes.

Convert Labels to Codes

1.

Select the character column and select Cols > Utilities > Labels to Codes.
