Same key, different values: nested dicts of dicts - grep

Question

Borrowing an MWE from this question, I have a set of nested dicts of dicts:
{
"type": "A"
"a": "aaa",
"payload": {"another":{"dict":"value", "login":"user1"}},
"actor": {"dict":"value", "login":"user2"}
}
{
"type": "B"
"a": "aaa",
"payload": {"another":{"dict":"value", "login":"user3"}},
"actor": {"dict":"value", "login":"user4"}
}
}
{
"type": "A"
"a": "aaa",
"b": "bbb",
"payload": {"another":{"dict":"value", "login":"user5"}},
"actor": {"dict":"value", "login":"user6"}
}
}
{
"type": "A"
"a": "aaa",
"b": "bbb",
"payload": {"login":"user5"},
"actor": {"login":"user6"}
}
}
For dictionaries that have "type":"A", I want to get the username from the payload dict and the username from actor dict. The same username can appear multiple times. I would like to store a txt file with a list of actor (ID1) and a list of payload (ID2) like this:
ID1 ID2
user2 user1
user6 user5
user6 user5
Right now, I have a start:
zgrep "A" | zgrep -o 'login":"[^"]*"' | zgrep -o 'payload":"[^"]*" > usernames_list.txt
But of course this won't work, because I need to find login within the payload dict and login within the actor dict for each dict of type A.
Any thoughts?

Answer 1

I am assuming you have the payload and actor dictionaries for all entries of type A.
Parse out the user name from the payload entries and redirect them
to a file named payload.txt
Parse out the user name from actor entries and redirect them to a
different file named actor.txt
Use paste command to join the entries and output them the way you want it
