Table Structures and Column Definitions (Maintenance Log Sheet)

The main Maintenance Log sheet features a well-structured table with the following columns and data types:

Formulas Required

The template leverages essential Excel formulas to automate calculations and enhance efficiency:

• Next Due Date (Column E):
  Formula: =IF(D2="", "", D2 + F2)
  This calculates the next scheduled maintenance date by adding the maintenance interval to the last service date.
• Status Color Logic:
  Conditional formatting uses formulas like:
  =AND(E2 < TODAY(), G2="In Service") → Flags overdue tasks in red.
• Asset ID Generator (Column A):
  Uses a combination of formula and custom numbering: =TEXT(TODAY(), "YYMMDD") & "-" & TEXT(COUNTA(A:A)+1, "000")
• Alerts in Maintenance Alerts Sheet:
  Formula to pull upcoming or overdue tasks: =IF(AND(MaintenanceLog!E2<TODAY()+7, MaintenanceLog!E2>TODAY(), MaintenanceLog!G2="In Service"), "Overdue Soon", "")

Conditional Formatting Rules

To enhance visual tracking and immediate identification of critical tasks:

• Overdue Maintenance (Red Fill):
  Rule: =E2 < TODAY() → Applies when Next Due Date is in the past.
• Due Within 7 Days (Orange Fill):
  Rule: =AND(E2 < TODAY()+7, E2 >= TODAY())
• On-Time (Green Fill):
  Rule: =E2 > TODAY() + 7
• Status Highlighting:
  Use color coding for Status column—e.g., green for “In Service”, red for “Out of Service”.
