Is JSON correct? (merge cells on header)

Hello

I have an excel in the attachment

By seeing the spreadsheet. I created the json file (as restaurant_few.txt) on my own from scratch

But I have some problem with my "json file"

I have trouble with the header on top. For example:
For BBQ Pork Bun and it is in a merge cell.
Then the below two cells, one is sales volume, and the other is income.

How can I manipulate it. Please advice if there is any change for the "json file"

What's more Is my "json file" correct. if you see any problem or have any suggestion, please tell me

Thanks

The json code is at the bottom and also the attach text file

Hard to tell without seeing code.
