My purpose is:
I need to extract data from PDF Table(Ex. Bank Statements) and pass this as JSON Data through API to update database Table in cloud.
As a first step:
I am trying to extract data from PDF documents which is giving me a JSON string with this flow. But I need to extract the individual items of the table or only the required JSON items, for which I gave expressions for each item, in the apply to each loop.

Followed this tutorial for the same in which at the end he gets Item, Quantity, Rate, Amount values from the table using expressions.

But in my excel Book I am just getting JSON strings. Am I missing on anything or doing anything wrong here?

But he gets the Individual values for each Item in Table as below:

How do I achieve the same. Or are there any other approaches to achieve the same.
