Power Query is available in multiple products today (Power BI, Excel, Analysis Services, etc.) and serves an important role in cleansing and combining data from diverse sources.

Business Intelligence expert Joel Champagne will walk through two specific examples:
1) Aggregating IoT data (in JSON), passing through Analysis Services, and ultimately into a SQL Server data warehouse, and
2) Combining data from nearly 100 different Excel files (of various formats), using Power BI, SSIS, and finally, SQL Server.

You'll learn how to use Power Query to:

* Cleanse data from diverse data sources
* Transform data from hierarchical to tabular formats
* Use drag-and-drop until you can't - and then switch to Power Query
* Create Formula Language (M)
* And much more!
