Sankey Diagrams with Microsoft Excel

Almost everybody has the most popular spreadsheet tool Microsoft Excel on their PC, and can quickly visualize data as line graphs or pie charts. However, it does not offer any good possibility to create flows or Sankey diagrams based on the data.

What are Sankey diagrams?
Sankey diagrams go beyond simple bar charts or pie charts: in addition to the actual values they can convey additional information, such as a hierarchical structure. Hence, material flows and energy flows can be visualized in a much more attractive way than it is possible with other (conventional) diagram types.

Another advantage is the visualization of branches, feedbacks and loops (recirculation) that are essential in energy flow charts, circular economy visualizations and material flow analysis.

Our Solution
The software e!Sankey includes an interface to Microsoft Excel. Thus you can just draw and generate your diagram using e!Sankey and link all flow values and other data such as text fields to your spreadsheets.

Full Automation of Sankey diagram generation
If you want to go the next step to a full automation, then the e!Sankey Software Development Kit (SDK) is the right solution.

In this example we can see energy in a wood gasification process.

The bar charts and pie chart illustrate all inputs and outputs at each process stage in detail. However, they don't reveal any information on the structure or sequence of the process steps, or about any feedbacks in the system, such as heat recovery.
