For many years, VLOOKUP has reigned supreme as the most widely used lookup function in Excel. But now that XLOOKUP is more widely available, VLOOKUP's reign will likely come to an end. XLOOKUP is a modern replacement for the VLOOKUP function and is more capable in almost every way. Let's look at how these two functions stack up against each other.

In this article, I attempt to explain why you see SUMPRODUCT so often in formulas, and when you can use the SUM function instead. The short version: SUMPRODUCT supports array operations natively, which makes it very useful for solving seemingly unrelated Excel problems. In the current version of Excel, you can use the SUM function instead, but SUMPRODUCT is better for backwards compatibility.

This article explains how to concatenate manually with the ampersand operator (&) and with the three Excel functions designed for concatenation: CONCATENATE, CONCAT, and TEXTJOIN.

In the world of Excel formulas, the term "array formula" is probably responsible for more confusion than just about any other concept. This is because the definition of an array formula has become mixed up with the requirement to enter some array formulas in a special way, with control + shift + enter.

There are eight widely used functions in Excel that use a syntax different from other functions in Excel. This syntax can make these functions more challenging to use, because it is not intuitive. Read on for important information about COUNTIF, COUNTIFS, SUMIF, SUMIFS, AVERAGEIF, AVERAGEIFS, MINIFS, and MAXIFS.

If VLOOKUP finds more than one match, will you get the first match or the last match? It's a trick question. It depends :) This article explains this confusing topic in detail, with lots of examples.

Most people never receive proper Excel training and spend years frustrated by the simplest tasks, especially tasks that involve formulas. To use Excel with confidence, you must have a good understanding of formulas and functions. This article introduces the basic concepts you need to know to be proficient with formulas in Excel.

The double negative coerces TRUE or FALSE values to their numeric equivalents, 1 and 0. This is a useful technique in many advanced formulas that work with cell ranges.

Criteria are a key concept in Excel, but building useful criteria for text, numbers, dates, times, etc. is hard because it requires a good understanding of how Excel handles data. This guide will help you build formulas that work the first time with over 50 examples.

Have you entered a formula, but Excel is not showing a result? This can be very confusing, and you might think you've somehow broken your spreadsheet. However, it's likely a simple problem. With a little troubleshooting, you can get things working again.

Working with formulas takes time, and too often a problem that seems simple ends up taking far too long. In this article, I share tips that will save you time when working with formulas in Excel.

INDEX and MATCH is the most popular tool in Excel for performing more advanced lookups. This is because INDEX and MATCH are incredibly flexible – you can do horizontal and vertical lookups, 2-way lookups, left lookups, case-sensitive lookups, and even lookups based on multiple criteria. If you want to improve your Excel skills, INDEX and MATCH should be on your list. See below for many examples.

One of the most useful features of data validation is the ability to create a dropdown list that let users select a value from a predefined list. But how can you make one dropdown dynamically respond to another? In other words, how can you make the values in a dropdown list depend on another value in the worksheet? Read on to see how to create dependent dropdown lists in Excel.

Data validation can help control what a user can enter into a cell. You can use data validation to make sure a value is a number, a date, or to present a dropdown menu with predefined choices to a user. This guide provides an overview of the data validation feature, with many examples.
