How to Make a Decision Tree in Excel | Lucidchart Blog
Skip to main content

Imagine that you’re sitting in a meeting with your company’s executives. You have decided that it will be more profitable for the company to build out a new software feature than to leverage an existing one—you have the data to prove it—but now you have to convince your leaders. And your spreadsheet of numbers is putting them to sleep.

Transform your data into a more interesting, more convincing decision tree diagram in Excel. Decision trees provide a more consumable layout for your data as you consider different options, and then they help justify your decision to others. This guide outlines two approaches to make a decision tree in Excel:

Option #2: Make a decision tree in Excel using the shape library or SmartArt

If you’re still set on making a decision tree manually in Excel, you can do so using either the shape library or SmartArt. Each of these options is more time-consuming and will be harder to customize than a decision tree created in Lucidchart. 

How to make a decision tree using the shape library in Excel 

Microsoft’s shape library allows you to build a decision tree using individual shapes and lines. 

  1. In your Excel workbook, go to Insert > Illustrations > Shapes. A drop-down menu will appear. 
  2. Use the shape menu to add shapes and lines to design your decision tree. 
  3. Double-click the shape to add or edit text. 
  4. Save your spreadsheet.

To use data to build your decision tree, you will need to conditionally format the cells with the appropriate data and use formulas to determine the correct output for your decision tree.

How to make a decision tree using SmartArt in Excel  

SmartArt graphics make it easy to create simple diagrams in Excel, but they are rigid and hard to edit and customize. Follow these steps below to use SmartArt:

  1. In your Excel workbook, go to Insert > Illustrations > SmartArt. A pop-up window will open. 
  2. Go to “Hierarchy” diagrams, select the one that fits your needs, and click “OK.” 
  3. Double-click “Text” to modify the text or use the text pane. 
  4. Select the graphic, and click “Add Shape” to make the decision tree bigger. 
  5. Save the spreadsheet once you’ve finished your decision tree.

Advantages of choosing Lucidchart

Speaking of decisions, let’s talk about why Lucidchart is your best choice for making a decision tree in Excel.

  • It’s intuitive. Drag shapes onto the canvas, instantly connect them with lines, and add your text. It’s simple and easy. 
  • It’s professional. You can line up your shapes more easily and change styling like colors and fonts for a more personalized, professional diagram.
  • It’s easy to import. Because Lucidchart integrates with Microsoft Office, you are only a few clicks away from transporting your decision tree to your Excel spreadsheet.

While it is possible to manually make a decision tree in Excel, it is a rigid process that makes it difficult to customize and update your decision tree. With Lucidchart, you can quickly edit and use templates to make decision faster and visualize your choice.

Now it’s time to make your own decision.
