Hmm Rory,- well yes, I guess so. I should explain what prompted my current musings I suppose. I inherited a file that had months across the top, and loads of projects and cost areas down the left with the little boxes filled in with numbers. Not exactly pivotable or useful in many ways. Although it didn't take long I added a column for 'months' and copied the categories 12 times. Rather than cut and paste the numbers into one column I thought 'I can do this more quickly with a bit of OFFSET, MATCH, throw in a bit LEN, RIGHT etc to taste and a pinch of LOOKUP.'
I am the only person who will ever use this data, although I will now be running reports from it that I will distribute. I have no need to do anything else with it - so my formulas were now just taking up space, so needed to go. It just hurt.
I have been burned by the odd 'please make it so my numbers change again' questions a few times. Agh.
I recognise that I am real geek/nerd for this stuff, which makes it even harder to call someone over and say 'Hey, look at THIS!' Maybe we should have a thread here to post things that we are proud of that may be worthy of admiration. You guys would understand!
