Formulas Required

The template uses essential Excel formulas to maintain automation and accuracy:

• End Date Calculation: =Start_Date + Duration - 1 (adjusts for inclusive date counting).
• Status Color Logic: =IF(Status="Completed","Green",IF(Status="In Progress","Yellow","Red")).
• Total Tasks Count: =COUNTA(Tasks!B:B).
• Completed Task Counter: =COUNTIF(Tasks!G:G,"Completed").
• Overall Progress (Weighted):
  =SUMPRODUCT((Tasks!G:G="Completed")*(Tasks!H:H), Tasks!I:I) / SUM(Tasks!I:I)
  (Assumes Duration column is named "Duration" and Progress % is in H).

Conditional Formatting

To enhance visual clarity, the following conditional formatting rules are applied:

• Gantt Chart Bars: Color-coded based on task status (Red: Not Started, Yellow: In Progress, Green: Completed).
• Status Column (Tasks Sheet): Text color changes dynamically—red for "Not Started", yellow for "In Progress", green for "Completed".
• Deadline Alerts: If Start Date is within 3 days, highlight the row in light orange.
• Overdue Tasks: If End Date is before today and Status ≠ "Completed", flag in red.
