Sadly using the totally wrong tool for the job. Using excel as a database.. sigh. So many times at work I've been asked to help out some hobby bob who painted themselves in a corner and made a 'tool' that ended up in production but was architecturally completely inadequate.

Especially in the days of 65536 rows and 256 columns this was a disaster waiting to happen. And also the 'Can whoever has orders.xls open please close it, URGENT!!' emails. Both issues are now fixed but it's still the wrong tool for the job.

Lotus Notes led to similar horrors.



If I'm not misremembering I'm fairly certain Excel still has hard limits on rows and columns.


It does yes! But it's in the millions now, not tens of thousands.
