Dynamic row count in Helper Table for Miracle method

My use case is as follows.

I have a 3rd party which does reporting for me, it gives me campaign stats, Sentimental analysis (It reads comments on my posts and gives me sentimental analysis)

I have a list of campaigns, I am calling an API every day morning to fetch the JSON in which there will be all the data including Array of comments and sentiment score for each campaign.

When I query and parse the data I will be able to get all comments in one column’s cell.

But Using the miracle method I can write each item of array into a seperate row right ?

But for that I would have to keep adding extra rows in the table so that they keep getting written to inidivudal rows rather than everything in single cell

For my use case it becomes cumbersome right?

Let me know if this gives better clarity?

Sorry I might not be good in explaining things.

Thank you for your patience.
