Find Dirty Data in Excel with Power Query

Показать описание
Finding outliers and dirty data in Excel files is not the easiest thing in the world but with the profiling tools in Power Query you can easily quickly profile large datasets to get to the root of data problems. You can then correct the issues in Power Query before loading back to Excel.

I show an example of this process in the video below and would really recommend that accountants get comfortable poling their data for errors before starting analysis.
