The Power Query Formula Language is a powerful query language optimized for building queries that mashup data. It's a functional, case sensitive language similar to F#, which can be used with Power Query in Excel, Get & Transform in Excel 2016, and Power BI Desktop. To learn more, see the PowerQueryName reference.

For computer language theorists: Power Query is a mostly pure, higher-order, dynamically typed, partially lazy, functional language. You can create a variety of data mashup queries from simple to advanced. As with any programming language, you will need some intermediate programming experience for more advanced scenarios.
