Trello JSON Export Missing Card

[Colleen Barkey]

I export my trello into json - i do not have business class trello yet, and last quarter i imported the json into Power BI and created a spreadsheet that was then used to see how many days it takes to complete an assignment. This quarter the export from Trello has changed - there is no "Card" history it is gone.  I am wondering where the data is now stored in the json export.  DO i know have to buy business class in order to have that item?

As you can see below there was a cards that had a list attached to it.

This is the most current export - no cards added ixUpdate:

Any help would be greatly appreciated!

Thanks
