Table Structures and Columns

Data Collection Log (Main Input Sheet)

Gantt Chart Dashboard

This sheet contains a visual timeline generated from the data in "Data Collection Log". It uses a matrix layout with dates across columns and tasks along rows. Each cell represents one day, and color-coded blocks indicate task duration.

Formulas Required

• Completion %: =IF([@Target]=0, 0%, IF([@Data Volume Collected] > [@Target], 100%, ([@Data Volume Collected]/[@Target])*100%) )
• Duration in Days: =IF(AND([@Start Date]<>"", [@End Date]<>"", [@End Date] >= [@Start Date]), ([@End Date]-[@Start Date])+1, 0)
• Status Indicator (Color Logic): Uses nested IFs and VLOOKUPs to map status codes to icons or colors.
• Current Status Flag: =IF(TODAY() < [@Start Date], "Pending", IF(TODAY() > [@End Date], "Overdue", "In Progress"))
• Auto-Timestamp: =NOW()

Conditional Formatting Rules

• Status Highlighting: Apply color scales: Red for "Overdue", Yellow for "In Progress", Green for "Completed".
• Gantt Cells: Format cells in the Gantt timeline using a rule to shade cells from Start Date to End Date with varying opacity based on task priority (High, Medium, Low).
• Deadline Alerts: Highlight any task where End Date is within 3 days of today.
• Data Volume Thresholds: Color code entries where Data Volume Collected exceeds target by more than 120% in bright green to flag overcollection.

User Instructions

1. Open the template and enable macros (if prompted) for full functionality.
2. Navigate to the "Data Collection Log" sheet and begin entering data in the appropriate columns.

Example Rows

Recommended Charts and Dashboards (Gantt Chart Integration)
