It depends on which procedure you are going to use to perform the
analysis.  If you use GLM Repeated Measures, you need one row per
subject, with the repeated measures appearing in multiple columns.  On
the other hand, if you use MIXED, you need one row per observation of
the dependent variable, which means multiple rows per subject, with
variables to indicate which time-point or condition applies for that
measurement.

You might try Googling on <SPSS repeated measures ANOVA>.  There are
plenty of tutorials online.
