Data input

How to get your flow data into the builder.

#Flow table

Each row in the flow table describes one flow: source, target, value, and an optional previous value (used for period-over-period change labels). The node list and chart layout are generated automatically from these rows — you never define nodes separately.

#Pasting from a spreadsheet

Click into the flow table and paste cells copied from Excel, Google Sheets, or any tab-separated data. SankeyKit reads source, target, value, and (if present) a fourth previous-value column.

#Adding rows manually

Use the + Add row button to add flows one at a time, typing the source, target and value directly into the table.

#Node styling

Once your flows are entered, the node list on the right lets you rename, recolor, and add a subtitle to each node — see Styling your chart.
