Analysts lose hours every week fixing dates, trailing spaces and mismatched labels before any real analysis can start. This episode is for Excel users and data teams who feed Power BI and Power Automate. It shows how Copilot in Excel can normalize, validate and transform data with a few prompts so cleanup stops being manual work.

Key takeaways
Worth quoting
“Excel was never meant to be the world's data hub. It was built for grids, not governance, a sandbox for accountants that somehow became the backbone of global analytics.” – Mirko Peters (01:15)
“Excel's architecture encourages this disaster. It has no schema enforcement, no input validation, no relational discipline.” – Mirko Peters (03:09)

Key takeaways
- Excel's flexibility without schema or validation is the root of inconsistent data that breaks Power BI, Power Automate and Fabric downstream.
- Copilot in Excel only edits the sheet when you move beyond chat and give it clear commands to normalize, validate and transform data.
- Embedding Copilot prompts at the start of every dataset's lifecycle turns cleanup into an automatic preflight check and frees analysts for real analysis.
