How to Make a Sankey Diagram
From data to finished diagram in three simple steps — faster than any Excel method.
Define Your Nodes
Add the categories in your flow — sources, processes, and outputs. Give each a name and an optional color.
e.g. Revenue, Cost of Goods, Gross Profit, Operating Expenses, Net Income
Set Your Flow Links
Connect nodes with directional links and assign a value to each. Link width scales automatically to reflect magnitude.
e.g. Revenue → Cost of Goods: 4200 | Revenue → Gross Profit: 5800
Customize & Export
Adjust colors, labels, spacing, and transparency. Then download your Sankey as PNG or SVG or share it with a link.
e.g. Switch to gradient flows, increase node spacing, download for your pitch deck

Frequently Asked Questions
Can I make a Sankey diagram in Excel?
Excel does not have a built-in Sankey diagram type. You would need a third-party add-in or a complex stacked bar chart workaround, which is time-consuming and hard to maintain. MakeCharts offers a dedicated Sankey diagram maker that works instantly in your browser — no add-ins required.
How do I make a Sankey diagram without Excel?
With MakeCharts, you can build a Sankey diagram in under two minutes. Add your nodes (categories), define the flow links between them with values, and your diagram renders live. You can also describe your data in plain language and let the AI generate the diagram for you.
What data do I need to create a Sankey diagram?
You need two things: a list of nodes (the categories or stages in your flow) and a list of links (connections between nodes with a numeric value). For example: 'Revenue to Cost of Goods: 4200' defines one link. MakeCharts walks you through adding both step by step.

Yes. The core Sankey diagram maker is completely free with no sign-up required. You can create, customize, and download your diagram at no cost. Pro plans unlock file upload, higher AI credits, and embed codes for websites.
