Let’s see a super simple example, to demonstrate how Pivot Tables work. Consider this dataset:
You want to summarize the data and answer questions like: how many apartments are there in the dataset? What’s the total cost of all the apartments?
Now, this would be easy to do with formulas, using a COUNTIF and a SUMIF, but if you change our mind and now want to summarize “Condo” you have to modify all your formulas, which is a pain.
Enter the Pivot Table:
This took me eight mouse clicks and I didn’t have to write a single formula (in a few paragraphs I’ll show you those exact 8 clicks so you can build your own version).
This Pivot Table summarizes the data for each property type. It counts how many of each property type is found in our dataset and then totals up the sales prices, to give a total sales price value for each property type category.
For example, the seven rows of data for Apartments are combined together into a single line in our Pivot Table (click to enlarge):
In technical parlance, the Pivot Table aggregates our data.
Why use Pivot Tables?
Pivot Tables are unrivalled when it comes to analyzing your data efficiently.
They’re flexible and versatile and allow you to quickly explore your data.
Pivot Tables are generally much quicker than formulas for exploring your data:

2. Click somewhere inside your table of data (I’m not counting this click 😉)
3. Click the menu Data > Pivot table... (clicks one and two)
This will create a new tab in your Sheet called “Pivot Table 1” (or 2, 3, 4, etc. as you create more) with the Pivot Table framework in place.
4. Click Rows in the Pivot table editor and add Property Type (clicks three and four)
5. Click Values in the Pivot table editor and add Property Type (clicks five and six)
6. Click Values in the Pivot table editor and add Sales price (clicks seven and eight. Boom! 👍)
Here are the steps in sequence:
And that’s it!
Eight clicks and you have a summary report of your dataset that gives you fresh insights into your data.
Now granted this is a super simple dataset, but even if we’d had hundreds, thousands or tens of thousands of rows of data, it would still be the same eight clicks to create this Pivot Table.
Let Google build Pivot Tables for you
Leverage the power of Google Sheets’ built-in AI!
When you create your Pivot Table, you’ll notice that Google automatically suggests some pre-built Pivot Tables for you in the editing window:
With a single click you can then create a Pivot Table:
It’s a neat way of quickly building them out as a starting point, and if it happens to answer your questions then even better.
Google Sheets also has the Explore tool, which can build Pivot Tables automatically for you. You can access the Explore tool from the star shaped button in the bottom right of your Google Sheet:
This opens the Explore window, where you can select from the suggested Answers (1) or even access a suggested Pivot Table (2). What is suggested and shown here is dependent on your data.
Clicking on a suggested answer will take you to a second window from where you can insert your automatically-generated Pivot Table (3):
I would absolutely still advocate learning how to build your own Pivot Tables however.
Even if you intend to always use the automatic Pivot Table builder, it’s still a good idea to understand how they work so that you know what the data is showing you.
So let’s take a look at building Pivot Tables in more detail.
2. Pivot Tables: Fundamentals
When you create a Pivot Table from a table of data, all of the columns from the dataset are available to use in your Pivot Tables.
Rows, columns and values
At the heart of any Pivot Table are the rows, columns and values.
When you click Add under the Rows, you’re presented with a list of column headings from your table. When you select one, the Pivot Table will add all of the unique items from that column into your Pivot Table as row headings. Recall from the example above, it takes all the rows of property data and squashes it down to just four rows, which are the four unique property types we see.
Adding Columns produces the same effect as adding Rows, but in for the columns. The Values data is displayed in aggregated form, for each column.
When you click on Values, you’re presented with the same list of column headings. When you select one, you’re telling the Pivot Table to summarize that column. For example, if it’s a list of revenue you might want to sum it up, or average it. Or, if it’s a column of text values, you may want to count them. This is what happens when you add values: the data is summarized, i.e. all the individual values from each row are combined together into single value (they’re aggregated).
If you have anything in the Rows section of your Pivot Table, the aggregation will be done at that level (e.g. if we have property types in Rows, the Pivot Table will display the aggregated values for each Property Type).
You can also drag-and-drop the fields in your Pivot Table to easily move them around, for example from Rows to Columns, as shown in this GIF:
You can easily toggle totals on or off for any of the Values columns in your Pivot Tables.
The button is in the Rows section:
The sort options are found in the Rows section of your Pivot Table.
Each Row field can be used to sort with, and each one has their own sort options.
First, choose which Row field you want to sort with under the Sort by menu option (1). Then you’ll have a choice of sorting by the category field itself or any of the value fields that have been aggregated for this category column (2). This image shows this:
The second option for sorting data is Order (3) where you specify whether you want it ascending or descending (4):
In this example, I’ve elected to sort by the second column, the SUM of Sales Price, and then chosen to sort descending so the whole table is sorted so that the largest values in this column are at the top and the smallest values at the bottom.
3. Pivot Tables: Tips and Tricks
To show you a few more tricks with Pivot Tables, we need an extra column in our data table:
So far, we’ve just looked at a single values column, showing a sum of the sales prices.
However, you can add more value columns. For example, you might want to count how many properties are in each category or what the average sales price was for each category.
Click Add in the Values section of the editor to add as many value columns as you want:
By adding the property type column (which is all the text values in our original data), the Pivot Table will default to counting the number of times each property type occurs (using the COUNTA function).
You can drag the values fields to rearrange the order of the columns in your Pivot Table.
Changing aggregation types
You can add the Sales Price field again, so that you have it twice in your Pivot Table. Initially it’ll default to SUM in both cases, giving you identical total columns. Not particularly useful.
However, you can change the aggregation type of one of the columns, e.g. change the SUM to AVERAGE instead, and then you’ll get fresh insights:
The aggregation options are accessed by clicking where its says SUM (or AVERAGE or whatever you’ve selected) and then choosing from the menu:
Pivot Table filters are conceptually the same as ordinary filters we use with our data.
We add a filter to show only a subset of our data based on some condition. For example, maybe you want to only see data from 2018, or just the month of September, or from Region A, etc.
They’re easy to add and use in Pivot Tables.
It’s the last section of the Pivot Table editor that we haven’t talked about yet.
Consider this example showing a count of properties for each property type:
It shows all 15 properties from the original dataset.
Add a filter by clicking Add in the Filter section:
In this example I’ve chosen the Agent column to add as my filter. This means that I want to choose to look at the data from just one of the Agents in my Pivot Table, i.e. filter down to show only that Agent’s data.
To filter on Jenny only for example, click on the “Status > Showing all items” and uncheck the items you want to discard. Whatever is left selected (shown with a tick) is the data that will be used to create the Pivot Table.
The output shows only the six properties for which Jenny was the agent:
Looking back at the data, what’s happening is that the Pivot Table is only including the rows of data related to Jenny in the Pivot Table, i.e. these six rows:
(Note: I’ve taken off the filter for this exercise.)
What happens when we add multiple fields to our Rows section? Let’s see.
The first field you add shows creates a unique list of items from that column. When you add a second row field, it appears as sub-categories, so that between the two columns in your Pivot Table, all the unique combinations of the two fields are shown.
Swapping the order of the row fields, by simply dragging and dropping them in the Pivot Table editor window, will swap the order of the categories.
For example, you can summarize the breakdown of property types for each Agent, or you can summarize the sales by each Agent for each Property Type.
Like everything with Pivot Tables don’t be afraid to just experiment here. Try different combinations and take a moment to understand what the Pivot Table is showing with each combination.
Copying Pivot Tables
Oftentimes you’ll find yourself wanting to replicate a Pivot Table, perhaps as a starting point for further data exploration.
There’s a quick trick for copying an existing Pivot Table, rather than starting over. It also gives you the option of moving your Pivot Tables to a different tab.
Click into the top left corner cell of your Pivot Table and click copy (Cmd + C on a Mac, or Ctrl + C on a PC/Chromebook). This adds the Pivot Table to your clipboard and you can paste it wherever you want in your Sheet (Cmd + V on a Mac, or Ctrl + V on a PC/Chromebook).
Note: You need to ensure there is enough space available wherever you wish to paste a copy of your Pivot Table (i.e. enough empty cells) or you’ll see the #REF! error.
4. Pivot Tables: Next steps
The nice thing with Pivot Tables is that they’re really easy to experiment with. Just try adding different fields in different parts of your Pivot table editor to see what effect it has. You can always start over!
