The examples in this section are based on the following sample graph:

CREATE (:Person {json:'{a:[1,2,3]}'});

MATCH (p:Person)
CALL apoc.convert.setJsonProperty(p, 'json', {a: [4,5,6]})
RETURN p

Table 1. Results
p
(:Person {json: "{\"a\":[4,5,6]}"})

We can extract the JSON value from the node using apoc.convert.getJsonPropertyMap:

MATCH (p:Person)
RETURN apoc.convert.getJsonPropertyMap(p, "json") AS map;

Table 2. Results
map
{a: [4, 5, 6]}
