I believe that there is not easy solution. That is, SPSS there is not variable type percentage. So first you can use excel to convert percentage and after that to entry these data to SPSS or you can insert data in SPSS ( (without %) and after that use SPSS (Transform --> Compute) to convert in percentages.
