The pivot table is one of Microsoft Excel’s most powerful — and intimidating — functions. Powerful because it can help you summarize and make sense of large data sets. Intimidating because you’re not exactly an Excel expert, and pivot tables have always had a reputation for being complicated.

The good news: Learning how to create a pivot table in Excel is much easier than you might’ve been led to believe.

But before we walk you through the process of creating one, let’s take a step back and make sure you understand exactly what a pivot table is, and why you might need to use one.

In other words, pivot tables extract meaning from that seemingly endless jumble of numbers on your screen. And more specifically, it lets you group your data in different ways so you can draw helpful conclusions more easily.

The “pivot” part of a pivot table stems from the fact that you can rotate (or pivot) the data in the table to view it from a different perspective. To be clear, you’re not adding to, subtracting from, or otherwise changing your data when you make a pivot. Instead, you’re simply reorganizing the data so you can reveal useful information from it.

What are pivot tables used for?

If you’re still feeling a bit confused about what pivot tables actually do, don’t worry. This is one of those technologies that are much easier to understand once you’ve seen it in action.

The purpose of pivot tables is to offer user-friendly ways to quickly summarize large amounts of data. They can be used to better understand, display, and analyze numerical data in detail — and can help identify and answer unanticipated questions surrounding it.

Here are seven hypothetical scenarios where a pivot table could be a solution:

1. Comparing sales totals of different products.

Say you have a worksheet that contains monthly sales data for three different products — product 1, product 2, and product 3 — and you want to figure out which of the three has been bringing in the most bucks. You could, of course, look through the worksheet and manually add the corresponding sales figure to a running total every time product 1 appears. You could then do the same for product 2, and product 3 until you have totals for all of them. Piece of cake, right?

Now, imagine your monthly sales worksheet has thousands and thousands of rows. Manually sorting through them all could take a lifetime. Using a pivot table, you can automatically aggregate all of the sales figures for product 1, product 2, and product 3 — and calculate their respective sums — in less than a minute.

2. Showing product sales as percentages of total sales.

Pivot tables naturally show the totals of each row or column when you create them. But that’s not the only figure you can automatically produce.

Let’s say you entered quarterly sales numbers for three separate products …read more
