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
