Power Query Transformations

Preparing data sources for analysis using Power Query

Data is all around us. We get it from many sources and don’t always have control of its format or layout, which can make it difficult to analyse, draw insights from and visualise.

Power Query (part of Excel and Power BI) gives you the tools to connect to many data sources and apply transformations including merging, shaping and cleansing.

We are passionate about teaching skills that participants can put to practical use immediately. During this webinar we will show you a number of common data problems and demonstrate various transformation techniques that you can put into practice straight away.
