Sankey diagrams are a fantastic way to visualize data flows, making complex relationships and information easy to understand. Whether you’re looking to represent energy flows, budget distributions, or user journeys, mastering Sankey diagrams in Excel can significantly enhance your presentations and reports. In this guide, I’ll walk you through the process step by step and share some handy tips, common pitfalls to avoid, and advanced techniques for using this powerful visualization tool effectively.

What Are Sankey Diagrams? 🤔

Sankey diagrams are a type of flow diagram in which the width of the arrows is proportional to the flow rate of the data. They are particularly useful for showing how quantities are distributed, allowing viewers to grasp relationships quickly. Imagine trying to depict how funds move from one category to another — a Sankey diagram does this seamlessly!

Getting Started: Preparing Your Data

Step 1: Organize Your Data

Before you can create a Sankey diagram in Excel, you need to gather your data. It’s crucial to organize it in a tabular format. Here’s a simple example of how you might structure your data:

Step 2: Open Excel and Set Up Your Workbook

1. Create a New Workbook: Open Excel and create a new workbook.
2. Enter Your Data: Input your organized data into the spreadsheet, replicating the above format.

Step 3: Insert a Pivot Table (Optional)

For larger datasets, consider creating a Pivot Table to summarize your data:

1. Select your data range.
2. Go to Insert > Pivot Table.
3. Choose where to place the Pivot Table and hit OK.

This will help you analyze your data better before creating the diagram.

Step 4: Use a Third-Party Add-In

Excel doesn’t have a built-in function for Sankey diagrams, so you’ll need to use a third-party add-in. Follow these steps to get started:

2. Search for "Sankey": Use the search bar to find a suitable Sankey diagram add-in, such as “Sankey Chart for Excel.”
3. Install the Add-In: Follow the prompts to install the add-in.

Step 5: Create Your Diagram

1. Select Your Data: Highlight the data you wish to visualize.
2. Launch the Add-In: Go to the Insert tab again and find your Sankey diagram add-in.
3. Follow the Prompts: Click through the prompts to generate your Sankey diagram, ensuring that your source, target, and values are correctly assigned.

Step 6: Customize Your Diagram

After creating your diagram, you’ll want to customize it to fit your presentation style:

• Change colors to represent different data categories.
• Adjust the size and position of the diagram in your worksheet.
• Add titles or labels for clarity.

Final Touches

Once you're happy with the design, make sure to save your workbook! With your Sankey diagram completed, it’s time to put it to use.

Tips for Effective Sankey Diagrams

• Keep It Simple: Avoid clutter. Only include the most relevant flows to keep your diagram easy to read.
• Use Contrasting Colors: Different colors for different categories will help your audience easily distinguish between them.
• Test for Clarity: Show your diagram to someone who knows nothing about the data. If they can understand it, you’re on the right track!

Common Mistakes to Avoid ⚠️

1. Overcomplicating Your Diagram: Avoid adding too many sources and targets. It can confuse the viewer.
2. Neglecting Data Accuracy: Ensure your data is accurate and well-organized. Inaccurate data can lead to misleading diagrams.
3. Ignoring Audience Understanding: Tailor the complexity of your diagram to your audience. What works for one group may confuse another.

Troubleshooting Common Issues

• Sankey Diagram Doesn’t Display: Check if your data is properly formatted and that the add-in is functioning correctly.
• Values Not Represented Accurately: Make sure the 'Value' column is formatted as numbers, not text.
• Colors Aren’t Changing: If you're having issues changing colors, confirm you’re accessing the formatting options in the add-in correctly.
