How to store the list of arrays using EF

It is storing the last looping array only, Not all the looping array values.

I want to store all the looping array values. 

First thing, there is no need to put huge list in question description itself. 

 

Coming to the question,

You can use deserialize function from Json library and convert it to list of specific type. Once you have the list, you can proceed with EF by creating entity objects if you are not casting to specific type.
