One of the examples of heatmaps can be the visual representation of COVID-19 cases being registered globally. The following map shows the geographic distribution of the cumulative number of COVID-19 cases reported per 100,000 people worldwide. Darker shades of orange denote the most affected countries, and the light yellow hues indicate the opposite.

There are quite a few efficient ways to generate a heatmap, such as using readily available free heatmap generators like VWO’s AI-powered heatmap generator or integrated analytical tools. Microsoft Excel or Google Sheets is another great option to explore. Let’s dive right in!

Learn How To Create a Heatmap in Excel

When using Excel or Google Sheets, you can either create a heatmap by manually coloring each cell depending on its value or act smartly and enter a formula/function to do all the taxing work for you. We’d suggest you use the latter method to create a heatmap.

Let’s consider the dataset extracted from the above represented COVID-19 globally registered cases as an example to learn how to create a heatmap using the function—apply “Conditional Formatting.”

Country	Cases	Deaths	Confirmed Cases
US	639664	30985	422943
India	12380	414	10415
UK	98476	12868	69002
Brazil	28320	1736	21484
Philippines	5453	349	3142
Canada	28364	1010	18769
Netherlands	28153	3134	14539
Germany	130450	3569	56928
Australia	6458	63	1482
France	106206	17167	49217
Italy	165155	21647	54581
Pakistan	6505	124	4214
Spain	177633	18579	75497
Russia	24490	198	21713
Singapore	3699	10	2699
Indonesia	5136	469	3459
Israel	12501	130	6910
Malaysia	5072	83	2164

Step 1: Enter the data

Enter the necessary data in a new sheet. We entered the data above.

Step 2: Select the data

Select the dataset for which you want to generate a heatmap. In this case, it would be B2 through D19.

Step 3: Use conditional formatting

If you are using Excel, go to “Home,” click on “Conditional Formatting,” and select “Color Scales.” The color scale offers quite a few options for you to choose from to highlight the data.   

In our case, we’ve used the first option where cells with high values are colored in green and ones with low values in red.

If you are using Google Sheets, you will find “Conditional Formatting” under the “Format” option in the menu bar.

Then select “Color Scale” and choose the relevant colors for the midpoint, minpoint, and maxpoint.

Note: Use a color scheme that best matches your data interpretation needs. 

Step 4: Select the color scale

Once you select a color scale, you’ll see a heatmap as shown below:

In this color scale, Google Sheets assign a green color to the cells with the highest values and red to the ones with the lowest values. Meanwhile, the remaining values are assigned colors based on the descending value order showing a gradient of shades falling between green and red. And there you have it: your beautiful heatmap to analyze visitor experience and get more conversions.

While this was just one of the ways to generate a heatmap using Excel or Google Sheets, you can get as creative as you want to. It also gives you the leverage to drill down and create mapping views of specific data sets as well. However, if you’re planning to create heatmaps to study the performance of your website or particular pages, we’d recommend you to use more robust and integrated tools than Excel, such as VWO heatmaps. They not only help you see how visitors engage with your website but also highlight web elements that catch their attention or distract them.
