JSON to data and de-pivot for exampleset

I'm having a 'mare trying to get some data to de-pivot from json... 

The below process gets data from Poloniex in json format. The first row works fine and the exampleset is generated as I'd like, the other 2 (the orderbook and historical trades) I just can't get my head around. The Poloniex public api info is here https://poloniex.com/support/api/ but seems to be outdated. Any help would be appreciated.

I came across another post whilst trying to figure out how to use the json file which gave me the de-pivot, I also found one using the json -> xml & xpath way but it seems like json -> data and de-pivot should work.
