Power Pivot is a free add-in to the 2010 version of the spreadsheet application Microsoft Excel. In Excel 2013, Power Pivot is only available for certain versions of Office. It extends the capabilities of the pivot table data summarization and cross-tabulation feature with new features such as expanded data capacity, advanced calculations, ability to import data from multiple sources, and the ability to publish the workbooks as interactive web applications. As such, Power Pivot falls under Microsoft's Business Intelligence offering, complementing it with its self-service, in-memory capabilities.
