How to Create an Decision Tree in Excel

A Decision Tree is a diagram with a tree-like structure. It helps to understand the possible outcomes of a decision or choice.

We have an action at the top, and then there are many results of the work in a hierarchy, showed as leaves & branches.

You can create a decision tree in Excel. This article is a step-by-step guide on how to create a decision tree in Excel and EdrawMax.

How to Make A Decision Tree in Excel

There are two ways of making a decision tree in excel, and the first is to use basic shapes and lines to make a decision tree in Excel, while the other is to use a ready-made decision tree template.

First, let’s start with the basic shapes and lines!

Method 1: Making a Decision Tree in Excel Using Basic Shapes and Lines

Step 1:

Open Microsoft Excel on your computer.

Step 2:

Insert the data into the spreadsheet for which you want to create a decision tree.

There are two ways to create a decision tree in Excel. One is to use basic shapes and arrows, and the second is to use the SmartArt Graphics. 

First, we will create a Decision Tree using basic shapes and lines. Click the Insert tab and then select Text Box from the Text section. After selecting the Text Box, you will be able to draw the Text Box using the cursor. Insert your question in the Text Box. You can see a text box with a question in the picture below.

Step 4:

Now you need to draw outcomes/answers to the question. It is up to you how many answers/outcomes you have for a question/decision.

To insert a line, click Insert and then select Shapes from the Illustrations. Next, choose a Straight line. After inserting a straight line, attach a box/oval for the 1st outcome. Now add more ovals for other results. You can see two outcomes from the Decision in the picture below.
