In this video, we'll use MATCH to find the position of an item in a table, and the INDEX function to retrieve the value at that position in a two-way lookup.
In this video, we'll look at how to use the SUMIFS function with an Excel table, with a side-by-side comparison without a table.
In this video, we'll look at how use Boolean algebra in array formulas for AND and OR logic. This is a key skill when building dynamic array formulas.
In this video, we’ll set up the XLOOKUP function to perform an approximate match in order to calculate a quantity based discount.
In this video we look at how to group sample voting data into 10 year buckets, using a pivot table.

This article provides examples of public Coronavirus data you can download to Excel with Power Query. Each example has a link, a screenshot to show what the data looks like in Excel after being imported, and an Excel workbook.
A quick example of how to track testing for COVID-19 using Excel and publicly available data. In this project, the data is fetched and "shaped" with Power Query, then dropped back into Excel, where it can be refreshed with a single click.
