Table Structures and Columns (Gantt Timeline - Extended Sheet)

The Gantt Timeline (Extended) sheet is the heart of this template, structured as a dynamic timeline grid that spans weeks or months. The table structure includes:

Formulas Required

The template leverages several dynamic formulas to maintain accuracy and interactivity:

• Duration (Days): =IF(AND([@Start Date]<>"", [@End Date]<>""), [@End Date] - [@Start Date] + 1, "")
• Percent Complete Calculation: =IF([@Status]="Completed", 100, IF([@Status]="In Progress", [@[Percent Complete]], 0))
• Timeline Cell (Gantt Bar): Uses a combination of SUMPRODUCT, INDEX, and COLUMN() functions to render task bars. Example for week column:

  =IF(AND([@Start Date] <= $B$3, [@End Date] >= $B$3), 1, 0)

• Dependency Validation: =IF(ISERROR(MATCH(@Dependencies, Tasks[Task ID], 0)), "Invalid", "Valid")
• Project Completion Rate: =AVERAGEIFS([Percent Complete], [Status], "<>Completed", [Status], "<>In Progress") * 100

Conditional Formatting Rules

The template includes advanced conditional formatting to enhance readability and alert users to critical statuses:

• Status Coloring: Red for "On Hold", yellow for "In Progress", green for "Completed".
• Deadline Alerts: Orange fill with bold text if a task is within 3 days of its due date.
• Gantt Bar Visualization: Each day column uses data bars to represent task duration (filled cells = active period).
• Overdue Tasks: Strikethrough formatting for tasks with end dates before today and status not "Completed".
• Milestone Highlighting: Purple border and bold font for milestone tasks.
