Sheet Names

The template includes the following key sheets:

• Maintenance Log (Main Data): The central sheet containing all maintenance records for a given year.
• Project Summary: A high-level overview of projects, including total maintenance hours, cost summaries, and key performance indicators (KPIs).
• Monthly Summary: Aggregated data by month to provide monthly trend analysis.
• Dashboard View: A visual summary with charts and key metrics for stakeholders.
• Formulas & Validation Rules: Contains a reference section with all formulas, data validation rules, and error handling logic.
• User Instructions: Detailed guidance on how to use each sheet effectively.

Table Structures and Column Details

The main Maintenance Log sheet contains a structured table with the following columns:

Data Types and Validation Rules

All columns are validated for data integrity:

• Date of Maintenance: Date data type with validation to accept only valid dates (e.g., between Jan 1, 2024 – Dec 31, 2024).
• Maintenance Type: Dropdown list with options: Preventive, Corrective, Inspection.
• Priority Level: Dropdown: Low/Medium/High/Urgent.
• Status: Dropdown: Completed, Pending, On Hold.
• Currency (Cost): Number format with currency symbol ($), 2 decimal places.
• Log ID: Auto-generated using a formula starting with "MAL-YYYY-" followed by sequential numbers (e.g., MAL-2024-001).

Formulas Required

The following formulas are embedded in the template:

• Auto Log ID: = "MAL-" & TEXT(YEAR(TODAY()), "0000") & "-" & TEXT(ROW()-1, "000") to generate unique IDs.
• Monthly Total Hours: =SUMIF(DateRange, MONTH(A2)=MONTH($A$2), Duration) for monthly aggregation.
• Total Annual Cost: =SUM(Cost Column) in the summary sheet.
• Priority-Based Filter Count: =COUNTIFS(Priority, "Urgent") to identify high-risk tasks.
• Due Date Status Checker: IF(DATE(2024,12,31) - NextDueDate < 30, "Overdue", IF(NextDueDate < TODAY(), "Urgent", "Upcoming")) to flag overdue tasks.

Conditional Formatting

The template uses conditional formatting to highlight critical data:

• High Priority Tasks: Yellow background when Priority = “Urgent” or “High”.
• Overdue Tasks: Red background if Due Date < TODAY() and Status is not "Completed".
• Status Tracking: Green for "Completed", Orange for "Pending", Gray for "On Hold".
• Cost Over $1,000: Highlighted in blue to draw attention to large expenditures.
• Monthly Trends (in Monthly Summary): Gradient color fill based on maintenance volume (low → high).

User Instructions

How to Use:

1. Open the template and navigate to the Maintenance Log sheet.
2. Enter data for each maintenance event using the defined columns. Use dropdowns for consistency.
