Data Entry and Structure Mistakes
Mixing currencies in the same column Never enter USD and CNY values in the same cost column without a currency label. Use separate columns for original currency and converted amount, or add a currency code column.
Inconsistent product naming Nike Air Max 90, AirMax90, and Nike AM90 will appear as three different products in your dashboard. Create a master product list and copy-paste names exactly.
Deleting rows instead of marking status When an order cancels, change the status to Cancelled rather than deleting the row. Deletion breaks formula references and corrupts historical totals.
Skipping the backup habit At minimum, download a local copy of your Google Sheet monthly. Excel users should use cloud backup services. One corrupted file can erase months of work.
Formula and Calculation Errors
Hard-coding totals instead of using formulas If you type a total number manually, it will never update when quantities change. Always use SUM formulas so your totals stay accurate automatically.
Broken VLOOKUP ranges When you add rows above a VLOOKUP range, the formula may not include new data. Use absolute references and structured table formats to prevent range drift.
Circular references A cell that references itself, directly or indirectly, creates a circular reference error. These crash calculations and are hard to trace. Use error-checking tools to find them.
Ignoring division by zero Profit margin formulas divide profit by cost. If cost is zero, the formula returns an error. Wrap calculations in IFERROR() to display clean messages instead of broken cells.
Workflow and Maintenance Errors
Letting the sheet grow forever A spreadsheet with ten thousand rows becomes painfully slow. Archive old data to a separate History tab or file every quarter to keep your active sheet fast.
Sharing edit access too widely Every editor is a potential data destroyer. Use comment access for most collaborators and reserve edit rights for yourself or your most trusted partner.
Never reviewing the Dashboard tab The Dashboard only provides value if you look at it. Schedule a ten-minute weekly review to spot trends, flag anomalies, and adjust your strategy.
