Project ID	Text (e.g., OFF-2024-001)	Unique identifier for each office management project.
Task Name	Text	Description of the task or milestone (e.g., "Order HVAC Units").

Priority Level	List: Low, Medium, High, Critical	Determines urgency and resource allocation.
Estimated Effort (Hours)	Numeric (decimal)	Expected time to complete the task.
Actual Effort (Hours)	Numeric	To be updated as work progresses.
Milestone Indicator	Yes/No (Boolean)	Check if this is a key milestone.
Dependency (Task ID)	Text or Reference to another task ID	Sets sequential logic between tasks.

2. Project Timeline Sheet

This sheet provides a Gantt-style visual timeline, automatically populated from the "Tasks & Milestones" data. Built using conditional formatting to draw visual bars across a calendar grid.

Column Name	Data Type/Format	Description
Task Name (from Tasks & Milestones)	Text (linked)	Dynamically pulls task names.
Start Date (linked)	Date
End Date (linked)	Date	Automatically calculated based on start and duration.
Milestone Flag	Yes/No (Boolean)	Circled or highlighted icons for milestones.
Status Indicator	Color-coded text/icon (e.g., red/yellow/green)
Duration (Days)	Numeric	Formula: =End Date - Start Date + 1.
Gantt Bar Range	Bar Chart Series (hidden formula-based range)

Formulas Required

The template uses dynamic formulas to ensure automatic updates and real-time tracking:

Duration Calculation: =IF(End_Date<>"", End_Date - Start_Date + 1, "")
Status Indicator Logic: =IF(Status="Completed", "Green", IF(Status="Overdue" & TODAY() > End_Date, "Red", IF(TODAY() >= Start_Date & Status<>"Completed", "Yellow", "Gray")))
Progress Percentage: =IF(Actual_Effort=0, 0%, IF(Actual_Effort > Estimated_Effort, 100%, (Actual_Effort / Estimated_Effort) * 100%))
Milestone Marker: =IF(Milestone_Indicator="Yes", "M", "")
Dependency Validation: =IF(ISERROR(VLOOKUP(Dependency, Task_ID_Column, 1, FALSE)), "Invalid ID", "OK")

Conditional Formatting Rules

The template includes smart visual cues to enhance readability:

Status-Based Color Coding: Red for overdue tasks; Yellow for in-progress tasks past due; Green for completed.
Gantt Chart Bars: Applied using "Data Bars" formatting on the timeline grid, with color gradients based on project phase.
Milestones: Diamond-shaped icons highlighted in gold to distinguish them visually from regular tasks.
Priorities: Color tags for High/Critical tasks (red/yellow background).

Begin by entering project details under the Tasks & Milestones sheet.
Use the provided drop-down lists for Status, Priority Level, and Milestone Indicator to maintain consistency.
