I took some pieces from my proof-of-concept code, your original data set, a recreation of your other data set, and produced this SAS program. It puts each record into a JSON container in a format that is probably close to what you want. I am still not completely clear on your desired JSON output. But you should be able to modify my code to get exactly what you want. Note that my code could be more concise. I wanted to make it understandable to someone not familiar with the techniques used. If you are uncertain, the proof-of-concept code I borrowed from contains many comments explaining the code.
