This two-day course covers advanced ways to extract, transform and load data, including learning a host of Power Query transforms, learning how to link to APIs, data flows and other data sources and how to work with parameters.  If your data is perfect (and you just want to learn how to present it well) this course is not for you, and you should consider attending our Advanced Power BI Reports course instead (classroom or online).

Sample customer feedback

Our thanks to everyone who agreed to share their thoughts (note that some of these reviews may be for our online courses).

"Wise Owl are brilliant at virtual training which cannot be easy currently. I had my doubts it would be as effective as a classroom, but I was reassured with the pre-test before the course and it turned out to be. The admin was brilliant and our trainer was excellent and patient despite my HP laptop with no mouse. "

Gary Meyler (Department for Levelling Up, Housing and Communities (DLUHC, ex MHCLG))

"Fantastic course and a fantastic trainer. The entire process from booking through to logging on was simple, straightforward and hassle free. I would highly recommend Wise Owl. 10/10!!"

Jon Clay (Girls' Day School Trust)

"Engaging course & exercises are a good way to learn; course manual very well written and supportive. Impressively made graphs and coding interesting. "

Matt Saunders (Bloom Services)

"Trainer made a dry subject very interesting and engaging."

Marion Israel (Warner Bros Entertainment UK Ltd)

"Training session was great, if anything I slightly found the remote sessions a bit better than when I went to Manchester for the in class training sessions. Great trainer. I have previously used Wise Owl course and they were great."
