The differences between those 2 versions of Excel are minimal.
Normally code written on the oldest supported system will work on the newer.

As the why "the macros do not work", I suspect it is something to do your
code, but you did not post the problem area(s), it is anyone's guess.

Hello experts,

I have prepared a workbook including macros for several users. The
workbook is prepared in Excel 2002. The problem is that some of the
users are working in Excel 2003 and here the macros do not work. Is
there a way to fix so the macros work in both versions?
