This file http://data.neo4j.com/northwind/suppliers.csv is loaded in the Northwind example.
Unfortunately, the CSV has extraneous commas in some of the fields (columns) causing values to appear under the wrong column header. A simple fix is to replace all ", " with just " ".
I just discovered that the same holds for the file "orders.csv".
Occurrences of commas in certain fields are not escaped by double quotes.
So either remove them or correctly escape them.
By the way, all is good here: developer-resources/data/northwind at gh-pages · neo4j-documentation/developer-resources · GitHub
