I'm an engineer/scientist and I find it super hard to follow other people's excel files. All you see if some data/numbers instead of the actual code/calculations.
Following spreadsheets is like trying to find something in my garage if all of the boxes have lids. But if the boxes are all open, I can find stuff in a jiffy, even if the boxes are disorganized.
It does display formulas, but by hiding the values. What my macro does is allow the formula to be displayed permanently in its own column.
Granted I'm one user out of many, and have switched to programming for any kind of quantitative work. but I'm still quite supportive of Excel.
But they couldn't figure it out either so it's limited to data formatted as table.
