The document discusses 5 common mistakes made when creating spreadsheets and how to avoid them. These include: 1) hardcoding numbers instead of using cell references, 2) inputting values incorrectly, 3) using inconsistent formats for cells of the same type, 4) creating spreadsheets that are too long and complex, and 5) not clearly explaining the calculations in the spreadsheet. The document recommends verifying formulas use cell references, double checking values, standardizing formats, breaking calculations into sub-spreadsheets, and clarifying mathematical operations in cell descriptions.

2. Mistake #1Mistake –Hardcode numbers in the formulaHow to avoid?Flip the page (Ctrl + ~) and verify that all formulas contain only cell values

3. Mistake #2Mistake –Input values are wrongHow to avoid?Double check the values before finalizing the spreadsheetAsk for someone to review

4. Mistake #3Mistake –Using different types of formats for the same type of cells How to avoid?Define a default format under “Formal Cells” optionUse “Format Painter” feature to align formats of cells from the same type

5. Mistake #4Mistake –Create a cumbersome and too long spreadsheetHow to avoid?Break the sub calculations into sub-spreadsheetUse only relevant and not just FYI values in the summary sheetKeep the summary spreadsheet to fit one screen

6. Mistake #5Mistake –Not explain operators in the flow of calculations (what is the mathematical operation I am using on the row above)How to avoid?Clarify what the operation is in the row description (e.g. + Net Income, x Tax Rate)
