  • No more copy and paste of data.
  • No more links to source files.
  • No more repetitive and manual data processing.

Second part demonstrates 6 basic skills in data transformation with Power Query:

  • Remove columns.
  • Remove rows.
  • Promote headers.

the instructor clearly knows Excel, but as a novice to power query I feel like the course moved a bit too fast. the main benefit of the course is that I have a high level understanding of the power query application and how it can make work more efficient. however, i would need to review the course while practicing w/n power query to really understand how to make use of the functionality covered in the course.

This course has great instruction of some complicated features. It would be great to have some more complex examples with additional time reflecting a more slow work-up.. but otherwise, learning lots! I did not see my test score pop up.. just that I passed.. would have been nice to see and know.. but I'm certain to revisit these scenarios

I learned a few things from this course, but I thought it was a little basic. I am hoping it can be built upon in the next courses. Lenny was an effective communicator, so I will be happy to check out his other courses.

The best class I have even taken on power query. Great examples, excellent instruction. Highly recommended. I will try PQ on some of my current data sets.

Most useful info for real world application. I found myself slightly uncomfortable following the steps vs having things drag out forever.
