Because everyone having to include huge swathes of unsupported third-party RouterOS functions to do such a common task is not a good look 
I’m probably not the only one that would really appreciate first-class support for parsing JSON objects in RouterOS scripts.
Thanks, guys!
Mikrotik added :serialize and :deserialize commands in v7 which support JSON. I’ve not tested to see if it handles nested arrays.
Yes, it does. Look for @Amm0’s detailed explanations and examples on the matter.
Brilliant! Thanks. Not sure why I didn’t spot this in the docs earlier.
I have an example of using :serialize/:deserialize with /tool/fetch for the pushover app’s JSON API here:

The approach work for most JSON API with a change of the URL used inside the function and different array of data provided.
