Very Quickly Define Power Query

Get and Transform Data (Office 2016 rename) Power Query is a (downloadable) data analysis feature available for Excel that lets you discover, combine and refine data

With Power Query, you can Find and connect data across a wide variety of sources. Merge and shape data sources to match your data analysis requirements or prepare it for further analysis and modeling by tools such as Power BI, Power Pivot and Power View. Create custom views over data. Use the JSON parser to create data visualizations over Big Data and Azure HDInsight. Perform data cleansing operations. Import data from multiple log files. Perform Online Search for data from a large collection of public data sources including Wikipedia tables, a subset of Microsoft Azure Marketplace, and a subset of Data.gov. Create a query from your Facebook likes that render an Excel chart. Pull data into Power Pivot from new data sources, such as XML, Facebook, and File Folders as refreshable connections. With Power Query 2.10 and later, you can share and manage queries as well as search data within your organization.
