I don’t want my readers to cause the next financial meltdown.
So what can we do?
1. Don’t hide cells (duh!) Ideally, we would design spreadsheets in such a way that nothing needs to be hidden. Usually when we hide cells it’s because they contain either inputs or calculations and we only want to show the resulting output. We want to show the answer, but not our work.
Sometimes this isn’t practical. So here’s another idea:
