*(Q) I need to retain the leading zeros of zip codes when I import my Excel data file into SPSS. Can you tell me how to do this? When SPSS opens my Excel data file, the leading zeros are lost. I need them in order to merge 2 files. *(A) Since you need the leading zeros to match, it means your zip codes are strings. The following code converts numbers into strings with leading zeros. * Posted to SPSSX-L lsit by Raynald Levesque on 2002/03/12. DATA LIST LIST /zipnum. BEGIN DATA 2 125 2364 62514 END DATA. LIST.
