Table Structures and Data Types

Sheet 1: Project Timeline (Gantt Chart)

This is the visual heart of the template. It uses a grid-based Gantt chart layout where rows represent tasks and columns represent calendar days (or weeks).

• Row Headers: Task names (text, up to 100 characters).
• Column Headers: Dates from start date to end date, formatted as "Mon 01/29". Columns are dynamically generated based on the project duration.
• Data Cells: Boolean values (True/False) indicating whether a task spans that specific day. Formulas auto-populate these cells based on the start and end dates from Sheet 2.

Sheet 2: Tasks & Milestones

This sheet holds all project data in structured table format. It is designed as an Excel Table (Ctrl+T) for easy filtering, sorting, and formula integration.

Formulas Required

• Duration (Sheet 2): =IF(End_Date <> "", End_Date - Start_Date + 1, "")
• Progress % (Sheet 2): =IF(Status="Completed",1, IF(Status="In Progress",0.5,0))
• Gantt Bar Logic (Sheet 1):

  =AND($C2 <= $A$1, $D2 >= $A$1)

  This formula checks if the current date column ($A$1) falls within the task's start and end range.
• Timeline Health (Sheet 3):

  =COUNTIFS(Tasks[Status], "Completed") / COUNTA(Tasks[Task ID])

  Calculates overall progress across all tasks.

Conditional Formatting Rules

• Gantt Cells: Use a gradient fill (light blue to dark blue) for active tasks; gray if not in range.
• Status Column (Sheet 2): Color-coded with:
  • Red: Not Started
  • Yellow: In Progress
  • Orange: On Hold
  • Green: Completed
• Milestones: Apply a diamond-shaped icon in the Gantt chart with bold red border.
• Dates approaching deadline (within 3 days): Highlight yellow background.

User Instructions

1. Set Your Project Dates: In Sheet 2, enter a start date in the first row. The Gantt chart will automatically extend based on task durations.
2. Add Tasks: Use the "Tasks & Milestones" sheet to insert new tasks. Assign owners and set start/end dates.
3. Update Progress: Change the status column to reflect real-time progress (e.g., from "Not Started" to "In Progress").
4. Customize Colors & Timeline: Modify column width, add new date columns, or switch from daily to weekly view.
5. Review the Dashboard: Monitor overall project health and critical path risks.
