This document provides tips for organizing data in spreadsheets. It recommends keeping data and formulas separate by clearly marking or separating them. Formulas should have one link each and reference data locally rather than through multiple links, for robustness and simplicity. Additional tips include always including units with numbers, especially financial ones, and avoiding exceptions in formulas by having one formula per row or column.
