This is a series of posts and exercises from a recent full-day workshop called Next Level Power BI. Check back for additional lessons and freely post your questions and feedback in the comments section after this post. Power Query is a modern data acquisition and transformation technology and it is the „Get Data“ component of Power BI and many other Microsoft tools. The query script language of Power Query is known as „M“ or the Microsoft Data Mashup language. The menu options and selections in the Power Query Editor interface build this „M“ script for you but to use Power Query at an expert level, you must understand fundamental concepts of the language. The post will step you through some essential mechanics of the language to build the necessary fundamental skills.
