I have to create summary reports on a regular basis for a dataset with millions of records. I learned about PowerPivot a few weeks ago and can use that to create my own PivotTables, but I'd like to create something dynamic within Excel that my end-users can easily use without having to install PowerPivot or any extra add-ins. Ideally, I'd like them to be able to sift through all of the data with filters and slicers. Any ideas what my options are?
