When using LOAD CSV or
neo4j-admin import if your data contains quotes they must be properly
escaped to be imported otherwise one might encounter the error
neo4j-admin import error

Caused by:ERROR in input
data source: BufferedCharSeeker[source:/home/neo4j/neo4j-enterprise-3.3.0/bin/hr.csv, position:59, line:2]

original error: At /home/neo4j/neo4j-enterprise-3.3.0/bin/hr.csv:2 - there's a field starting with a quote and whereas it ends that quote there seems to be characters in that field after that ending quote. That isn't supported. This is what I read: 'Bill"'
LOAD CSV error
LOAD CSV WITH HEADERS FROM "file:///hr.csv" AS row FIELDTERMINATOR ',' CREATE (n:Staff { staffid: toInt(row.id), staff_name: row.name});
At /home/neo4j/neo4j-enterprise-3.3.0/import/hr.csv:2 - there's a field starting with a quote and whereas it ends that quote there seems to be characters in that field after that ending quote. That isn't supported. This is what I read: 'Bill"'
For the above case my hr.csv is defined as
id:int,name:string,supervisor:int
1,Emil Eifrem,1
2,"Bill" William Smith,1
3,Dana Canzano,2
And the failure is with parsing line 2 and as a result of the line starting with a ". In order to import the above into Neo4j and
have line 2 be recognized as "Bill" William Smith the data needs to be reformatted to
id:int,name:string,supervisor:int
1,Emil Eifrem,1
2,"""Bill"" William Smith",1
3,Dana Canzano,2
The data will then successfully import as evidence
