For a hacky solution, I've often just used grep, tr, awk, etc. If it's a well structured file and all the records are the same or similar enough, it's often possible to grep your way into getting the thing you want on each line, and then use awk or sed to parse out the data. Obviously lots of ways this can break down, buy 9GB is nothing if you can make it work with these tools. I have found jq much slower.
