Data organization in spreadsheets
1 worksheet, 1 type of data
Don’t mix (import) data and formulas
Better: clearly mark them
Even better: separate them
Multiple links in one formula are
unnecessarilycomplex
One link per formula
Keep it local
More improvement is possible
Why is this risky?
Better idea?
More robust: couple with VLOOKUP
We can still do (a bit) better!
Always add units, especially for
financial numbers
Suppose we want to add a discount
column
Don’t go against the flow
Something else is off here
No exceptions in formulas
One per row or column
