Power Pivot helps you overcome Excel’s limitations when it comes to working with massive datasets. Using the add-in you can import over 1 million row datasets, from virtually any source. However, that’s not all. Power Pivot is also really handy for creating pivot tables from multiple datasets. You’ll not have to bother with vlookup and you can forget about multiple consolidation ranges.
Power Query can save you a lot of time when working with imported data. Often, when data is imported from external sources, it needs work on it, before it can be used. Unnecessary rows and columns may need to be removed, blank spaces may need to be deleted, and data may have to be merged or split. All of this can be done on Excel, but with Power Query, things move a lot faster. It can also handle much more data and you can save query definitions on it to increase ease of usage in the future.
And, here’s the best part, they are FREE! In fact, most 2013 and 2016 Excel users already have access to PowerPivot and PowerQuery, but need to take steps to enable them.
