Table Structures & Column Definitions

All data tables use Excel Tables (Ctrl+T) for dynamic expansion, structured references, and formula consistency.

Maintenance_Log Table

Campaign_Data Table

Required Formulas

• Log_ID: In column A of Maintenance_Log, use =ROW()-1 for auto-incrementing IDs, assuming headers start at row 1.
• Conversion_Rate_%: In Campaign_Data, use =IF([@Leads_Generated]>0,[@Budget_Spent]/[@Leads_Generated],0) to calculate cost per lead (reverse logic).
• Budget_Utilization%: Create a calculated column: =IF([@Budget_Allocated]>0, [@Budget_Spent]/[@Budget_Allocated], 0).
• Version_History: Use =NOW() and =ENCODEURL(CELL("filename")) to auto-log template version updates when saved.
• Rolling 90-Day Spend: In Dashboard sheet, use =SUMIFS(Campaign_Data[Budget_Spent], Campaign_Data[Date_Activated], ">="&TODAY()-90).

Conditional Formatting Rules

• In Campaign_Data, apply red fill to cells where Budget_Utilization% > 110% (overspending).
• Apply green fill for Conversion_Rate_% above 8% and yellow between 4-8%, red below 4%.
• In Maintenance_Log: Highlight rows with Change_Type = "Budget" in orange, "Timeline" in blue, "Channel" in purple.
• Apply data bars to Budget_Spent column based on allocated budget percentage.

This Excel template is not a static document — it is a living record of your Marketing Plan’s evolution. By enforcing disciplined use of the Maintenance Log and maintaining strict Data Version control, marketing teams can prove ROI with evidence, justify budget decisions with audit trails, and continuously refine strategy based on real-world results rather than assumptions. This approach transforms marketing from an art into a measurable science — where every change is documented, every decision is traceable, and every improvement builds upon the prior version.
