Power Pivot is a function of Microsoft Excel. It is available as an add-in in Excel 2010, 2013 in separate downloads and as an add-in with the Excel 2016 program. Power Pivot extends a local instance of Microsoft Analysis Services Tabular that is directly embedded in an Excel workbook. This allows a user to build a ROLAP model in Power Pivot and use pivot tables to explore the model once it is built. This allows Excel to act as a Self-Service BI platform, implementing professional expression languages to query the model and calculate advanced measurements.
