I have an excel file that has a variable called date of birth (DOB) that is in the following form Jun-58 to represent June 1958. The file has 11,000 cases which creates a myriad of DOB options. I have imported the data file into SPSS, a statistical package for the social sciences. SPSS does not have a data format option to recognize the DOB format produced in the excel file since it is alphnumeric with a dash. Is there an "easy" way to recompute the DOB into a numeric variable in excel, given the format that it is currently in?
