How to use it

  1. Three columns: source, target and amount, one flow per row.
  2. Use a target name again as the next source to chain stages, such as inquiries → quotes → orders.
  3. Hover a node to highlight its flows; drag nodes to adjust positions before exporting.

Data format example

Copying from a spreadsheet gives this format, with tabs between columns:

From	To	Leads
Google search	Inquiries	120
Inquiries	Quoted	165
Quoted	Orders	28

Frequently asked questions

How do I bring in data from Excel?

Select the range including headers in Excel, WPS or Google Sheets, copy and paste it into the data box; tabs are detected automatically, and CSV or comma- or semicolon-separated text works too. Thousands separators, currency symbols and percent signs are removed.

Is there a watermark? Can I put it in PowerPoint?

No watermark. PNG exports at twice the chosen size and SVG is vector, so both stay sharp in PowerPoint, Word or print; you can also copy the image and paste it directly.

Is my data uploaded?

No. Data is parsed and drawn in your browser. A share link carries the data after the # in the URL, which is never sent to the server; only people with the link can see it.

How do I prepare Sankey data?

One flow per row: source, target and amount, such as "Google search → Inquiries 120" and "Inquiries → Quoted 165". The same name in different rows becomes one node, multiple stages are laid out automatically and repeated rows are added together.

Why does it say the flows form a loop?

A Sankey diagram flows one way, so a loop such as A → B → A cannot be drawn. Rename the returning end, for example "Existing customers (repeat)", and it will display.

Sankey diagram maker practical guide and common questions

What does a Sankey diagram maker do?

Nodes with the same name merge, repeated source → target rows are added together, and rows whose source equals the target or whose amount is not above zero are skipped with a note.

Who is this for, and when is it useful?

Marketing, operations and finance staff tracing where traffic turns into inquiries, quotes and orders — and where it leaks — or where budget and energy go.

How do I use this Sankey diagram maker?

One flow per row: source, target, amount; stages connect automatically, repeated rows add up and loops are flagged.

How should I interpret the results?

Sankey diagrams flow one way; a loop such as A → B → A is reported with its path, and the returning end needs a new name.

Where is the work performed, and which services receive data?

Merging flows, checking loops and drawing all happen in your browser; conversion data is never sent to a server.
