Use Excel's AI to Build a Payroll Reconciliation Template

What This Does

Excel's Copilot feature can build a reconciliation template that automatically compares your payroll register totals to GL entries and highlights any variances, turning a 2-4 hour manual check into a 20-minute process.

Before You Start

• You have Excel open (Microsoft 365 subscription required for Copilot)
• You have your payroll register export and GL extract ready
• You're logged in with your Microsoft 365 account

Steps

1. Open a new Excel workbook

Start with a blank workbook. In the first sheet, set up two columns: Column A for your payroll register totals by department or cost center, Column B for your corresponding GL entries.

2. Open Excel Copilot

Click the Copilot icon in the lower-right corner of the Excel window. A Copilot panel will open on the right side of your screen. Microsoft moved Copilot off the Home ribbon in 2026, so the corner button is now the one entry point; press F6 if you prefer the keyboard, and right-click the button and choose Move to ribbon if you want it back up top.

3. Ask Copilot to build the reconciliation logic

Type: "Create formulas to compare Column A (payroll register) to Column B (GL entries) and highlight any row where the difference exceeds $10. Add a Column C that calculates the variance amount and a Column D that says 'OK' or 'REVIEW' based on whether it's within tolerance."

4. Apply the formulas

Copilot will suggest formulas for Columns C and D. Click "Insert" to add them to your sheet. The conditional formatting for highlighting will be applied automatically.

5. Review and use the result

Each row where Column D says "REVIEW" is a discrepancy you need to investigate. Sort by Column C (variance) descending to tackle the biggest gaps first.

Real Example

Scenario: You ran payroll for 3 departments this period and need to reconcile to the GL before month-end close.

What you type to Copilot: "I have payroll totals in A2:A20 and GL entries in B2:B20. Highlight rows where the difference is more than $1 and show me the variance amount."

What you get: Columns C and D automatically calculate variance amounts and flag which rows need investigation, in under 2 minutes.

Tips

• Always paste your data as values (not formulas) from the payroll system to avoid circular reference errors
• Add a "Notes" column next to the REVIEW flags so you can document why each variance exists
• Save this as a template and reuse it each period; just paste in fresh data
