What is a decision tree in Excel?

You can use an Excel decision tree as a visual tool to assist in making decisions. Decision trees may be used by businesses, data analysts, C-level executives, and some individuals in their personal lives to guide their decisions regarding significant events. In Excel, you can link a decision tree to the information on a spreadsheet so that it updates as the data does, keeping the tree current. This can be helpful when data changes. Excel decision trees can also assist others in data interpretation and independent decision-making.

How to create a decision tree in Excel in 5 steps

There are several approaches to building a decision tree in Excel, all of which involve third-party applications. To create a decision tree in Excel, follow these five steps:

1. Choose a program to use with Excel

Selecting a program that integrates with Excel is the first step in creating a decision tree. A program called Visio is available in Microsoft 365 and integrates with the entire Microsoft Office family of applications. Outside of Microsoft, there are other options, such as:

Each of these applications can collaborate with Excel to produce a visual decision tree, which might assist you in making decisions based on the information you enter into your spreadsheet.

2. Enter the data into an Excel spreadsheet

The following step is to populate your spreadsheet with the information needed for the decision tree. This pertains to elements like each of the data’s “nodes” or “branches,” which are the decisions you might make during the process. Enter the information you require to guide the decision after you have added the options, such as monetary values, temperatures, weather conditions, or success metrics. The temperature, weather, and outfit options, for instance, are data you can include in a decision tree that determines what to wear based on the weather.

This information is crucial because the programs use quantifiable data from the Excel spreadsheet to guide their decisions as they build the decision tree. This is crucial even if you are only using the decision tree as a visual aid because, particularly if the data you use is numerical, the data in the tree updates based on the information in the spreadsheet. Filling the Excel spreadsheet with pertinent monetary values, for instance, can help you make the best decision possible for your company if you are using the tree to make a financial decision for a business.

3. Create dialog or text boxes that display information

You can create text or dialog boxes to display information about your options after entering all of your data into an Excel spreadsheet. Using the data you entered, you can use this to create a text or image display. The steps to insert text boxes and attach them to the appropriate cells in the spreadsheet are as follows:

4. Insert a starting condition for the decision tree to activate

To start the first decision, enter a condition in a cell close to the first text box. By keeping the crucial information close to the decision tree visual, this can make your spreadsheet appear more professional. The tree may act differently depending on which Excel program you are using. When using Visio and Excel, for instance, the tree remains a static visual aid you can use, but when using other programs, the tree may move or slightly change shape to suit the needs of those programs.

You can use an equation, a threshold, or a matching set of text within a cell as your starting condition. You can set that amount of money as the starting condition for the decision tree, for instance, if you work in finance and must have a certain amount of money available before deciding what to do with it. You could also start your decision tree with a formula like the “greater than or equal to” function or “MATCH.”

5. Design equations for each of the decisions the tree details

Designing equations for each of the text boxes you previously made is the final step in Excel decision tree creation. For instance, you can enter an equation into a blank cell of an Excel spreadsheet and then reference that cell in the text box to see the equation’s result. Along with Excel formulas and functions, you can also create and use cell references to create complex calculations and highlight particular text boxes based on the data you entered. This can help you make quick decisions using only the information you currently have.
