Neo4j has several exchange formats (a few csvs, graphml, ...), but none of them seem to work...
When I followed the (well-written) docs I couldn't find a single format that even passed a simple
round-trip test, i.e. export and import, even using their test data.
Instead, our exporter now creates a separate file for each node|edge type: the cypher query to read the _data.csv
as a csv and map it's columns to the correct properties, converting them to the correct value types.
