Monthly Gantt Chart Excel Template for Data Collection

This comprehensive Excel template is specifically designed to support Data Collection activities using a visual Gantt Chart approach, tailored to a Monthly planning and tracking cycle. It enables users to plan, monitor, and visualize data collection tasks across multiple months with precision and clarity. Whether you're managing market research projects, clinical trial data gathering, field surveys, or academic studies, this template provides an efficient system for scheduling activities while ensuring all collected data is systematically tracked.

Sheet Names

The template includes the following three sheets:

1. Data Collection Schedule (Gantt View): The primary sheet containing the monthly Gantt chart visualization, task list, and timeline.
2. Data Log: A detailed table for recording actual data collection entries, including timestamps, source information, and quality checks.
3. Dashboard & Summary: A consolidated view with key performance indicators (KPIs), progress tracking charts, and summary statistics.

Table Structures and Columns

Sheet 1: Data Collection Schedule (Gantt View)

This sheet contains the main Gantt chart layout. It is structured as follows:

The table is followed by a visual Gantt chart where each row represents a task, and the horizontal bars display the duration across calendar months. The timeline spans from January 1, 2024 to December 31, 2024 with monthly increments.

Sheet 2: Data Log

This sheet is dedicated to Data Collection and contains individual records of data points gathered during the project. It includes:

This log serves as a source of truth for all collected data, enabling auditability and verification. Each entry is linked back to its associated task via the Task ID.

Sheet 3: Dashboard & Summary

A dynamic summary dashboard featuring:

• Total planned vs. completed tasks (by month)
• Data collection progress bar (percentage of entries logged)
• Monthly data volume trends over time
• Task completion heatmap by team member

Formulas Required

The following formulas are implemented across the sheets to support automation:

• Gantt Chart Bar Length (in Schedule sheet): =IF(AND([@Start Date]>=DATE(2024,1,1), [@End Date]<=DATE(2024,12,31)), DATEDIF([@Start Date],[@End Date],"d"), 0)
• Progress % Calculation: =COUNTIFS(Data Log[Task ID Reference], "DCT001", Data Log[Validated?], "Yes") / COUNTIF(Data Log[Task ID Reference], "DCT001")
• Status Indicator (Automatic): =IF(TODAY() > [@End Date], "Overdue", IF(TODAY() >= [@Start Date], "In Progress", "Not Started"))
• Monthly Data Volume (Dashboard): =COUNTIFS(Data Log[Date Collected], ">=1/1/2024", Data Log[Date Collected], "<=1/31/2024")

Conditional Formatting

To enhance readability and visual tracking:

• Status Column: Color-coded using rules:
  • Not Started → Light Gray (RGB: 240, 240, 240)
  • In Progress → Yellow (RGB: 255, 237, 167)
  • Overdue → Red (RGB: 255, 169, 169)
  • Completed → Green (RGB: 184, 240, 184)
• Gantt Bars: Bar color changes based on task status using a formula-based conditional format:
  • If Status = "Overdue" → Red border and background
  • If Status = "In Progress" → Yellow highlight with orange bar fill
• Dashboard KPIs: Conditional formatting on progress bars to turn green when ≥80%, yellow at 50–79%, red below 50%.

Instructions for the User
