Have you ever looked at a complex Excel spreadsheet written by someone else and tried to work out that the hell is going on?

It is really hard to work which sheets/rows/columns/cells are dependent of which other which sheets/rows/columns/cells. And that is before we even get to stuff like:

=FLOOR("5/"&DAY(MINUTE(YYYY/38)/2+56)&"/"&YYYY,7)-34

(and much worse)
