Excel as BI → Power BI
Stop running the business from brittle workbooks
When Excel is the real reporting system, someone spends Monday moving numbers by hand. A wrong paste becomes an argument. The charts do not answer the next question without a new file. Owners and operations leads feel that every week. We put the living model in Power BI so Excel is the export, not the system of record.
Why leave
Manual work, errors, and analysis that cannot move
Manual effort
Someone rebuilds the pack every week. That time should go to running the business. Power BI refreshes the model so a person is not the glue between files.
Human error
A wrong cell, a wrong paste, or the wrong version of the file burns the meeting. Finance and operations argue the numbers instead of the decision. A certified Power BI model takes that argument off the table when the definitions are shared.
Charts that cannot answer the next question
Excel charts stay flat. In Power BI, people filter and drill the same model instead of asking for another workbook.
Next step
Move the model out of Excel
Book a Session to decide which workbooks become Power BI first, and to land one certified slice while Excel becomes the export. See also Power BI migration.
