Can You Use the LET Formula to Define an Array in Excel?

Excel is a powerful tool for data analysis and manipulation, but sometimes its formula language can be complex and unintuitive. One common question users have is whether they can use the LET formula to define an array in Excel. This could simplify their calculations and make their spreadsheets more efficient. In this post, we will dive into this topic, illuminating the LET formula and providing practical examples.

Understanding the Problem

Imagine you have a list of totals that you would like to verify. You want to check if the maximum value matches the minimum value from different tables containing those totals. If they match, it implies that all values are the same. The challenge is to avoid repetition in the list of totals when evaluating the maximum and minimum values.

Original Formula:

The question arises: Can we use the LET function to define an array to represent our list of totals instead of repeating it?

The Solution: Using LET to Define an Array

The LET function in Excel allows you to assign names to calculation results. This can reduce repetition within formulas, leading to clearer and faster calculations. Let’s explore how to implement it:

Defining an Array with LET

You can redefine the list of totals using the LET function. Here’s how to do it:

In this formula, we:

Use the LET function to create a variable named Totals which contains an array of the sums from three different tables.

Calculate the minimum and maximum values from this array and evaluate if they are equal.

Alternative Methods

If you would like to manipulate the values differently, there are other ways you can achieve similar results:

Using CHOOSE Function

You can also define the sums in a single variable using the CHOOSE function like this:

Here, X acts as a reference for the individual sums created using the CHOOSE function.

Direct Assignment

Another direct approach is to create variables for each sum without forming an array:

This method assigns each sum to individual variables A, B, and C, and then checks if their minimum equals their maximum.

Conclusion

The LET function is a versatile tool in Excel that can significantly improve your formula efficiency and clarity. By defining an array, you not only streamline your calculations but also make your formulas easier to read and maintain. The examples provided illustrate different methods that can be employed, allowing you to choose the one that best fits your needs.

If you've been dealing with repetitive sums and comparisons in Excel, using the LET function can simplify that process dramatically! Try it out in your own spreadsheets to see the difference it can make.
