Advanced Power BI Data

Live online training course - classroom version also available

£795 + VAT (where applicable)

If your data needs a bit of work before you can use it properly, this course could save you time!  Whereas our two-day introduction course covers the basics of Power BI, this two-day advanced course shows you lots of advanced data modelling techniques, including:

  • Creating custom columns, index columns, columns by example and conditional columns
  • Appending, merging, unpivoting and transforming data
  • Creating and using simple and dropdown parameters
  • Understanding how to create and invoke custom functions
  • Loading data from HTML and JSON data sources
  • Linking to APIs
  • Getting data insights from the Power BI AI tools

If your data is in perfect condition, on the other hand, you should consider instead attending our two-day Advanced Power BI Reports course.

What other people have said

Many thanks to those listed below for kindly agreeing to let us use their names. All of the reviews are from the last 3 calendar years (although some may be for classroom courses):

"Very professional starting from the pre-course communication and pre-course materials received, to the course itself. The trainer was brilliant, nothing was too drawn out or overexplained but just enough to ensure it was understood, very methodical and professional. Thank you very much, I really enjoyed it and wouldn't hesitate to book on the next level course."

Trish Smee (Greater Manchester Combined Authority (GMCA))

"I really enjoyed the course. I think the content and pace was at the ideal level and the flexibility of the trainer, with structuring the days and allowing space for tangents, was much appreciated."

Dean Zahorodnyj (Atos)

"Great course. Pre check made sure everyone had the access they needed to start straight away. Set up was brilliant with the ability for the trainer to monitor everyone's progress. Our trainer was very friendly and knowledgeable and the training sessions were well managed."

Niki Fletcher (Manchester Metropolitan University)

"It was great to know that our trainer could see what we were doing remotely and track with us. A positive experience of an on-line training course. Thank you."

Beverley McNamara (Greater Manchester Combined Authority (GMCA))

How our live online training courses work

We've published a full summary of what it's like to attend a Wise Owl course online - here are the main things you need to know.

What you'll need

You'll need three things for the course:

  1. A computer (obviously) running Windows.
  2. A good internet connection.
  3. A microphone and (ideally) webcam.

In addition you'll find the course very difficult without an additional monitor (so that you can participate in the course on one screen, and use the software you're learning on the other).

What will happen when you book a place

Within a few hours of your booking a place on one of our online courses, we'll be in touch to get you set up correctly.  This usually takes about half an hour, and can be done at any mutually convenient date/time.

A few days before your course begins you'll receive a parcel in the post (free for UK bookings) containing:

  • A full colour courseware manual;
  • An exercise booklet to go with the course; and
  • A USB stick containing the files for the course, should you need a back-up.

Your parcel will even include a Wise Owl biro (they're good; trust us) and pad.

What you won't need

You won't need to install any software at all on your computer.  This is because:

  • you'll use Windows Remote Desktop to connect to our computers, and these will have all of the necessary files and software installed; and
  • we use Teams for our online training, which you can run through most modern browsers.
On and after the course

On the day of the course itself you will be able to join the course up to half an hour before it begins. This will give you time to:

  • familiarise yourself with the set-up;
  • meet your trainer; and
  • get to know the other delegates!

After the course finishes you'll receive an electronic certificate proving your attendance (we will gladly send a paper copy on request also).
