Use Excel Copilot to Analyze Energy and Maintenance Data

What This Does

Copilot in Excel helps you analyze your utility bills, work order data, and maintenance costs using plain language — generating charts, pivot tables, and trend analyses without needing advanced Excel skills. Turns raw numbers into management-ready insights.

Before You Start

• You have Excel open with your data (utility bills, work orders, or maintenance costs in a table)
• You're signed in with Microsoft 365 Business or Enterprise with Copilot enabled
• Your data is formatted as a Table (select your range and press Ctrl+T)

Steps

1. Format your data as a table

Your data must be in an Excel Table for Copilot to work. Select your data range including the header row, press Ctrl+T, confirm the range, and click OK. Headers like "Month", "Electricity_kWh", "Electric_Cost", "Gas_Therms", "Gas_Cost" work well.

2. Open the Copilot panel

Click the Copilot button in the Home ribbon (spark icon on the right). The Copilot panel appears on the right side of your screen.

3. Ask for analysis in plain English

Type natural language requests:

• "Show monthly electricity cost trend for the past 12 months as a chart"
• "Calculate which months had above-average energy consumption and flag them"
• "Show total maintenance spend by category for Q1 2026 and compare to Q1 2025"
• "What's the percentage change in energy costs year-over-year by utility type?"
• "Identify the 5 work order categories with the highest total cost in 2025"

4. Review and insert the result

Copilot generates the chart, table, or formula. Click Add to sheet to insert it. Then check the numbers against your raw data — spot-check 2–3 values before sharing with management.

Real Example

Scenario: Your CFO asked why energy costs spiked in August. You have 24 months of utility data in a spreadsheet.

What you type: "Compare August 2025 electricity consumption to the prior 3 Augusts and to the monthly average for 2025. Show as a table and write a 2-sentence management explanation for the variance."

What you get: A comparison table showing August consumption in context, plus a plain-language explanation you can paste directly into your email to the CFO.

Tips

• Rename your column headers to be clear and specific before using Copilot ("Electric_kWh" not "Column C") — it needs readable headers to understand your data
• Always verify totals and percentages by spot-checking against your raw data — share nothing with leadership that you haven't personally confirmed
• Use Copilot to create a reusable monthly energy dashboard: "Create a summary table with this month's totals vs. last month vs. same month last year for all utility types"
