• If it’s truly tabular, put it in a table. Structure what deserves structure
• Separate data, logic, and presentation. One job per sheet
• Every workbook gets an input sheet. Change values in one place only
• Break monster formulas with LET and LAMBDA. Name the steps, Reduce direct cell references. References should describe meaning, not location
• Add a README tab. Explain your why and how
• Use color with a system. Every color must mean something
