Excel has previously offered possibility to import XML files, but it was a rather tedious process because it was necessary to join the corresponding XML schema with the file. Although by definition it is simple, it often happened that my success, and others’ failure, could only be explained by the words: “Excel loves me and does not love you”. You will admit, this is not a fair explanation. Power Query maximally simplified this operation!
When you use Power Query to retrieve data often need to be “purified” before they can continue to be used in the reports. For this purpose you can use a tool called Query Editor.

Power Query is an Excel add-in that is used to retrieve data from various sources, connecting to them and purging data before we use them to create a report. It manipulates data in a worksheet, managed within structured table, and allows directly adding them the model. First release of Power Query was an optional add-in for Excel. In version 2016 it has become an integral part of the application. This technology is embedded in PowerBI service.
