Did you know...

SankeyBuilder is the only tool that creates Sankey diagrams automatically...upload your file and it scans each column of data and lays out the diagram! It will even detect a column of data with numeric values, and set that as the weight of the paths/links, you see in the Sankey diagram!

Some of SankeyBuilder's Exclusive features...Automatic Paging of large data sets with sit back and relax playback, the abiltiy to move Nodes and then Lock them into place...we call this Node Lock...SankeyTrend which allows you to include multiple values allowing you to playback Time Slots or even Pause and Resume Time! And of course you can make copies of a diagrams to create slightly different views from the same data. Like the look of a diagram? Refresh the values with our Update feature! Oh and then there is the drag & drop fields that allow you to change the data relationships on the fly.

Looking to style your Sankey diagram...sure...we have you covered! Adds Arrows to paths, color paths/links or even Nodes! Change the size of the font, adjust the scale of paths to make complex paths stand out, and even adjust Node spacing or width, and even animate paths to highlight areas of interest!

Now you can do everything!

Frequently asked questions

We have included the most common answers to questions we have recieved at SankeyBuilder. If you still have an unanswered question please try our Contact Us form at the bottom of this page.

Top Questions

Enter you email in the Email Address input box and click the Signup button. We will setup a Free plan for the entered email address and send you a 'welcome' email. Simply click or tap the login url to get started in the welcome email. If you like SankeyBuilder, select a paid plan, make payment and we will link the 'free' account to the appropriate paid plan.

You can upload your own data to support 1 diagram (one file) to try SankeyBuilder. SankeyBuilder automatically picks up to 3 fields from your data and 1 value. The tab to modify the selection of the value is disabled until you upgrade to a Paid plan.

The other limitation is the number of records it will display in the tool; which is limited to 10; however the paging bar is enabled allowing you to load 10 records at a time into a diagram. Other than that, everything else is enabled.

Upgrade to a paid plan to remove those limits and enable the Admin functionality that allows you Add or Remove diagrams, select additional Fields and Values, and load more than 10 records into a diagram.

Note: We periodically remove free accounts 30 days after signup. Upgrade to a paid plan to remove this limitation.
We recommend Google Chrome, FireFox or Microsoft Edge browsers. Currently they are the only browsers that support the full SVG spec and thus support all SankeyBuilder features.
Paid plans come with one Admin account. The Admin can distribute a Login URL to other users; which allows them to create Sankey diagrams on there behalf. Assistants have limited rights...only the Admin can remove a diagram with a SankeyBuilder Username and Password.

No we do not offer refunds...We feel that once you try the Free account, that should have given you plenty of time to try SankeyBuilder, and to make your executive decision.

If you are on a subscription based paid plan, you could cancel the subscription with PayPal at which time we will revert your account back to the Free plan after the paid period has ended.
