EXCEL FORMULA INTEGRITY VALIDATION USING POWER AUTOMATE
OVERVIEW
I built a Power Automate workflow to validate Excel financial models and alert errors in real-time. Excel Agent Mode can miss formula dependencies and reconciliation checks. This workflow ensures formula integrity and sends real-time email alerts when issues are detected.
FLOW LOGIC
- Trigger – Starts when an Excel file in OneDrive is modified
- List Rows – Retrieves validation table
- Filter Array – Keeps rows where Status = "Error"
- Initialize Variable – Prepares summary string
- Apply to Each – Adds each failed check
- Condition – Sends email if errors exist
- Send Email – Include bold red highlights for errors
SAMPLE EMAIL ALERT
A validation error was found in your financial model.
Net Income Flow-through: Error (11/04/2025 03:30)
Test Error Trigger: Error (11/04/2025 03:30)
Please review the Excel model and correct the issues.
USAGE INSTRUCTIONS
- Upload your Excel file to OneDrive with the validation table
- Update the Power Automate flow to point to the correct file and table
- Ensure the Filter Array step checks Status = "Error"
- Save and test the flow; errors trigger email alerts
- Optional: Customize the email template for formatting or recipients
WHY THIS MATTERS
- Excel Agent Mode may miss formula linkage or integrity issues
- Dependent relationships may be misinterpreted
- Workbooks may be modified without validation records
This workflow ensures:
- Formula integrity is maintained
- Errors trigger real-time alerts
- Audit trails are preserved
