Hi @kushwah.raja1

How to create nodes in nested array of JSON Neo4j Graph Platform

Hi, I just had the problem of storing a 3-dimensional array as a property. The way I did it is this: flattened the 3-dim array into a single array containing all the values (column-first) wrote a user-function to index into the array like this: f(x,y,z) = (x-1)ab + (y-1)*b + z where a and b are the dimensions of y and z. This, of course, only works if the dimensions are the same for each row. In your case the innermost dimension is always 2 (lon, lat), but the outer dimension which is a…

Thanks for the reply.

But in my case, the JSON file is very big. So finding it difficult to write the CQL.

Hi @kushwah.raja1

Have you tried the apoc library?, to maybe import the json data in a list form that might make it easier to create a cypher query around it.

Below link has some examples that might give you some idea to proceed.

Load JSON - APOC Documentation

This section describes procedures that can be used to import JSON data from web APIs or files.

Looking at your query and at the data you have attached, I am a bit confused as to why you want to load all the json as a single property on a Patient node. Ideally there would be different aspects of the json that should go into different components that in turn connect to each other through relationships, to fully utilize the graph.
Apologies if I misunderstood your design and requirement, but just trying to suggest the best option.
