This is amazing... Files that were difficult to hand over because they were complicated with Python in Colab can now be done so easily using Power Query,,, You explained just the key points so well, it's absolutely fantastic

Wow, it's really easy to understand and very good. Thank you. I'll listen comfortably first -> then listen again and try to follow along.

The best

Thank you for the great lecture!

It seems I've used Excel, unaware of so many features. I'm learning well.

RPA, was curious! Learned a lot! Thanks!

I work in the finance department, and Power Query is truly the best. This is my first time experiencing that it can even extract unique values.

Lately, the volume of data has been increasing and I was having difficulty with frequent errors in Excel, but thanks to your easy explanation of Power Query and Pivot Tables, I was able to apply them to my work! Thank you so, so much for the quick and easy explanation of only the most useful features!!! : )

Best course for beginners!
