I am trying to import csv data in table using below command COPY table1(col1,col2,col3) from 'file:///home/tab.csv' WITH (format= 'csv' , delimiter = ',') RETURN SUMMARY;

I am not getting any kind of error but in col3 it is getting stored as “,” seprated.

Data types of columns
col1 - int
col2 - text
col3 - Object

Below is sample data which is in csv
in col3 there is json data.
