Sankey charts are a type of diagram that can be used to illustrate complex networks of flow and interaction between various entities. These diagrams consist of a number of nodes that represent the entities and lines that connect them. The flow direction of these lines can indicate the direction of the data flow (from left to right or from top to bottom, depending on the orientation of the diagram).
Sankey charts are commonly used in various fields such as finance, engineering, and business to visualize data flows and interactions. Here is a comprehensive guide on how to create and apply Sankey charts in Excel.

First things first, open Excel and click on the Insert tab. Here, select the Sankey chart icon from the list of charts that appear on the page.

Next, choose your graph properties from the drop-down menu. You can choose from different sizes for the nodes, line width and color.

The flow direction of the nodes can be changed by selecting the node and clicking the arrow that appears under it. If the flow direction is not changing, click on the arrow once again to reverse the direction.

You can also change the scale by selecting the nodes and right-clicking to choose the option “Set scale…” from the drop-down menu. This will allow you to change the height and width of the nodes to fit the data.

To ensure that no nodes are overlapping, you can customize the placement of the nodes. Click and drag to adjust the positioning of nodes, and right-click to change or delete nodes.

Finally, add titles to the diagram and set the orientation (vertical or horizontal). Save the diagram.

Sankey charts are useful for visualizing a variety of flows and interactions. The flow direction of the nodes and the nodes’ positions can be used to provide additional context and insights about the data. For example, in the finance field, a Sankey chart can be used to explain the flow of financial transactions between different accounts.

Overall, creating and applying Sankey charts in Excel can be a powerful tool for understanding and analyzing complex data flows and interactions. With the simple steps outlined in this guide, anyone can develop a visually appealing and informative Sankey chart that can help them communicate complex information effectively.
