Microsoft recently announced that Data Explorer and Geo Flow are being merged into the new PowerBI suite.  You can download the new Power Query (formerly Data Explorer) and Power Map (formerly GeoFlow) from the link provided in the blog post below.

Power Query and Power Map are two of the new Excel features for Power BI announced this morning at the Worldwide Partner Conference. Together, these two tools enhance the self-service business intelligence experience in Excel by allowing you to discover, combine, refine and visualize your data. But as you will see in this post, self-service BI can become truly personal depending on the nature of the questions that you are trying to answer.

Note that Power Query was previously known as Codename “Data Explorer”. Similarly, Power Map was previously known as Project codename “GeoFlow”.
