SankeyGen is a free, browser-based tool for turning data into Sankey diagrams: budgets, funnels, energy flows, or any breakdown that moves through stages. No account required.

You can enter data directly or use this Google Sheets / Excel template to transform your data into a compatible CSV.

Rename any node with inline label editing. Just double-click it on the diagram. Save your session to pick up where you left off, and export the finished diagram as an image, a PowerPoint slide, or a swipeable Instagram carousel.
