Copilot Studio Agent for Excel Macro Modernization — Anyone Tried This?

Anyone built a Copilot Studio agent to analyze macro-enabled Excel workbooks (.xlsm) and recommend a modernization path — e.g., migrating logic to Power Automate or rebuilding as Power BI dashboards?

Curious about real-world attempts:

what worked, what didn’t, and where the ROI actually showed up. Would love to compare notes before diving in myself.
