I find a better rule that people should follow to not tell anyone if you are bad at it while your job is ‘doing excel’. Or tell you are good at it when you don’t even understand the basics. The number of excel sheets I have seen which contain hardly any formulas and errors trivially prevented with basic experts made by people who get paid big money to work with excel is cringing. Taking many hours to do things that take minutes even if you know some basics. And then when something changes, say, hourly rate, manually redo everything. I have not seen this once or twice but at least 100x from 100 different people who are supposed to know better. I don’t claim to be good at it but come on. I have too many anecdotes from both big and small companies that abused Excel in every way possible and every way is considered extremely bad practice. (Off-topic maybe) The other way as well; creating documents with 100s of sheets so complex they can be seen as a small neural net almost and then, because no one really understands it anymore, just connect it up to a webservice via OLE with ASP.NET and there we go. So… many… times…
