In this example, the goal is to get the minimum value for a given group above a specific temperature. In other words, we want the min value after applying multiple criteria. The easiest way to solve this problem is with the MINIFS function. However, if you need more flexibility (for...Read more
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...Read more
The goal is to generate a series of sequential dates with a formula. In the current version of Excel, the easiest method is to use the SEQUENCE function. SEQUENCE can return all dates at the same time into a range on the worksheet. In older versions of Excel without the SEQUENCE function, you...Read more
In this example, the goal is to sum every nth value by column in a range of data, as seen in the worksheet above. For example, if n=2, we want to sum every second value by column, if n=3, we want to sum every third value by column, and so on....Read more
In this example, the goal is to use XLOOKUP to find the first "red" or "pink" record in the data as shown. All data is in an Excel Table named data in the range B5:E14. This means the formulas below use structured...Read more
In this example, the goal is to calculate the maximum value that occurs in a set of data on a given weekday (i.e. Monday, Tuesday, Wednesday, Thursday, Friday).

In this example, the goal is to add days to a date. This is a frequent task in Excel when you need to calculate a new date by adding a specified number of days to an existing date. Here are some examples of situations where this might be useful:
In this example, the goal is to join two one-dimensional ranges together horizontally. This can be done with the CHOOSE function and array constant.
The CHOOSE function is used...Read more
The Excel WEEKNUM function takes a date and returns a week number (1-54) that corresponds to the week of year. The WEEKNUM function starts counting on the week that contains January 1. By default, weeks begin on Sunday, but this can be changed.Read more
The CHOOSE function provides the framework for this formula. Choose takes a single numeric value as its first argument (index_number), and uses this number to select and return one of the values provides as subsequent arguments, based on their numeric index.
In this case, we are using...Read more
In this example, the goal is to sum the smallest n values in a set of data, where n is a variable that can be easily changed. At a high level, the solution breaks down into two steps (1) extract the n smallest values from the data set and (2)...Read more
In this example, the goal is to calculate the average hourly rate per day based on the data shown. All data is in Excel Table named data in the range B5:F16. Note that we want to calculate a weighted average in this case. A weighted average hourly rate is the...Read more
The CHOOSE function does most of the work in this formula. Choose takes a single numeric value as its first argument (index_number), and uses this number to select and return one of the values provides as subsequent arguments, based on their numeric index.
In this case, we are providing...Read more
In this example, the goal is to retrieve the largest 3 (top 3) values in the named range data, which appears in the range B6:B16. The standard solution to get "nth largest values" is the LARGE function. However, one potential problem with LARGE is that it will return duplicate...Read more
The Excel TRIMRANGE function removes empty rows and columns from the outer edges of a range of data. The result is a "trimmed" range that only includes data from the used portion of the range. Because it is a formula, TRIMRANGE will update the range dynamically when data is added or removed...Read more
Note: In Excel 365, the new SEQUENCE function is a better and easier way to create an array of numbers. The method explained below will work in previous versions.

The article below walks through several options, from simple to very advanced. The more advanced options...Read more
In this example, the goal is to write a formula that will return TRUE if a year is a leap year and FALSE if not. This is a surprisingly challenging problem in Excel for two reasons: (1) Excel thinks 1900 is a leap year due to a long-standing bug inherited from Lotus 1-2-3 and (2) The logic for...Read more
The Excel WRAPCOLS function converts a one-dimensional array into a two-dimensional array by wrapping values into separate columns. The length of each column is given as the wrap_count argument: when the count is reached, WRAPCOLS starts a new column....Read more
The Excel WRAPROWS function converts a one-dimensional array into a two-dimensional array by wrapping values into separate rows. The length of each row is given as the wrap_count argument: when the count is reached, WRAPROWS starts a new row....Read more
At the core, this formula is composed of two sets of the COUNTIF function wrapped in the IF function. The outer IF + COUNTIF first checks to see if the value in question (B4) appears more than once in the list:...Read more
This formula depends on two helper columns. The first helper column holds random values created with the RAND() function. The formula in C5, copied down is:
