A picture is worth a thousand words.
- and quite a few numbers too.
But how valuable is a picture of this sort:
Until now such pictures – Sankey diagrams – were worth either a sisyphoic effort:
by piecing them together in a drawing program, only to redo them when the figures change.
Or you could alternatively pay a lot of money for specialised charting or visualisation programs that could do the trick.
MS Excel is unable to create Sankey diagrams – or better 'was unable':
Sankey Helper v2.4 helps you design Sankey diagrams from Excel data ... in Excel !
Advantages:
- Creates Sankey diagrams directly in MSExcel.
- Updated diagrams from changed data in no time.
- Based on the common MSExcel. No additional software necessary.
- Freeware resp. Sankey-ware: Send me a diagram, use it for free.
Disadvantages:
- Adjacent aligning of neighbouring fluxes can vanish when data changes.
- User-assisted naming of data cells necessary
- Ability in handling the standard drawing objects in Excel/MSOffice is required
Sample diagram
The picture above is an example of an elaborate Sankey diagram created with the assistance of Sankey Helper 2.4.
New in v2.4 is a One-step-default-diagram-macro straight from Excel tables. The default diagram can look like this:
Sankey Helper 2.4 comes as an Excel Workbook containing Visual Basic macros (VBA) and several
examples that hint at the versatility of this little miracle - if I say so myself.
Included is also a Read me/Manual as PDF document.
Again: Sankey Helper is almost free:
Send me one of your diagrams,
use it for free.

What's new in version 2.4?
- New macro for One-step-default-diagram as shown above
- Enhanced colouring features: colours from data cells, creation of colour hue variations
- Macro 'f_NewFlux' works on cell ranges too and resulting Sankey shapes are stacked nicely
Upcoming: SankeyTurtle
