SUMIFS

Sum a Column Based on Values in Another

By Jeff Lenning | May 22, 2019 |

In this post, we’ll learn how to add up a column of numbers based on the values in another column. For example, we are trying to analyze product sales based on average customer rating. That is, customers rate our products on a scale of 1 to 10, and so each product has an average rating…

We are in the middle of a series called Stop Wasting Time, where we are learning about Excel features that help us improve how we update a report. In the beginning of our journey, we were updating the report manually. Now, as we’ve learned more, we’ve been able to automate parts of it. That is,…

This is the second post in the Stop Wasting Time series. In this post, we learn how Power Query can help us update our report in less time. After all, why would we want to spend more time than necessary updating it? That is called “wasting time” and we just don’t like wasting such a…

By Jeff Lenning | January 10, 2018 |

Psychologist Abraham Maslow wrote a line that is often referred to as Maslow’s Hammer. It goes something like this: “I suppose it is tempting, if the only tool you have is a hammer, to treat everything as if it were a nail.” I’ve heard the simplified version more often: “If all you have is a…

VLOOKUP vs INDEX-MATCH

By Jeff Lenning | May 25, 2017 |

There are numerous lookup functions in Excel, and often, their capabilities overlap. And, that is true with many things in Excel…there are often multiple ways to accomplish any given task. Performing lookups is no exception. So, how are we supposed to know which lookup function to use? Often, Excel users try to decide between VLOOKUP…

Multi-Column Lookup with VLOOKUP and SUMIFS

By Jeff Lenning | September 17, 2015 |

When you need to perform a lookup, your instinct tells you to use VLOOKUP. But, when your lookup uses multiple conditions and columns, you may be inclined to use SUMIFS. However, when the value you need to return is a text string, rather than a numeric value, you are precluded from using SUMIFS since it only…

SUMIFS with OR

By Jeff Lenning | August 14, 2014 |

Of all the functions introduced in Excel 2007, 2010, and 2013, my personal favorite is SUMIFS. The SUMIFS function performs multiple condition summing. The function is designed with AND logic, but, there are several techniques that allow us to use OR logic instead. This post explores a few of them. Note: if your version of…
