VBA is the only way to integrated semi-advanced functionality into an Excel Sheet but it's so buggy that a few simple mistakes while developing a VBA Sub will cause the app to crash - doesn't feel like this has been available for decades but more like weeks.
And the worst? After Excel crashes you can't simply re-open the Workbook you were mediling with, it has to be "repaired" first which in most cases will go ahead and strip any random amount of the functions and VBA calls you're using in your tables without notice x.x
