How To Make a Google Sheets Heat Map: Easy 2024 Guide

A Google Sheets heat map is a great way to add color to a boring spreadsheet, making it much easier to read and more visually appealing.

Luckily, Google Sheets has simplified creating a heat map by using the conditional formatting feature, which highlights and customizes your data so you can choose your color scheme, making it easier to view.

Additionally, it’s also easy to set up. Navigate to “Format” > “Conditional formatting” > “Color scale,” and then fill in the “Midpoint” according to your preferences — Midpoint and Maxpoint.

Keep reading as I explain the alternative uses for a Google Sheets heat map and discuss the different methods to create heat maps.

Feel free to make a copy of my example spreadsheets to make it easier for you to follow the article as I explain the intricate details of using a Google Sheets heat map.

What Is a Google Sheet Heat Map?

A Google Sheets heat map represents data in a spreadsheet by color-coding the values in the cells. They can show the extremities in the dataset using a gradient color, making the dataset visuals more appealing.

The high and low values can be represented with extreme color variations, whereas the average values can be defined with mute colors. This allows users to identify the maximum and minimum values quickly and easily.

For example, I have a spreadsheet with the sales data range for various products in different regions. The cells contain the sales numbers for the products in the different areas.

Looking at raw, complex data can be tedious, especially with a large dataset. In such cases, I would make a Google Sheets heat map to filter and differentiate the data using shades of red and green.

Why Use a Google Sheets Heat Map?

I like to use a Google Sheets heat map in my spreadsheets for several reasons, such as:

Trend Identification

By using colors to represent values in the dataset, heatmaps help me identify patterns or trends in my data efficiently. For example, a heat map can help me see which products are underperforming in specific regions in a sales report.

Risk Assessment

A Google Sheets heat map is extremely helpful in identifying risks. I use them to identify the likelihood and potential impact of risks visually. This can be helpful in a stock portfolio template where a heatmap can show which assets are performing well and the ones that may need my attention.

Performance Analysis

Heatmaps are also helpful in work environments and can be used to analyze performance metrics like customer satisfaction or employee productivity.

Process Optimization

A Google Sheets heat map can be used to analyze workflows and processes. I use them to identify any bottlenecks in the process to improve them.

Now that I’ve explained some of the common use cases of heat maps in Sheets, let’s look at how to create one in my 2-minute video below! Or keep reading to see the step-by-step instructions.

How To Create a Heat Map in Google Sheets

There are multiple types of heat maps that you can create in Google Sheets. Below, I’ll show you several examples of heat maps in Google Sheets.

4. Choose the rule where you want to apply the values.
   • I highlighted all values under 4000 in this example and applied the “Less than or equal to” rule.
5. Once the rule is selected, enter the value in the textbox under the rule.
   • In this case, I wrote the numeral figure 4000.

6. With the rule defined, choose the “Formatting style” to apply to the cells that fulfill the specified condition.
