How to read line-delimited JSON from large file (line by line)

Just read each line and construct a json object at this time:

with open(file_path) as f:
    for line in f:
        j_content = json.loads(line)

This way, you load proper complete json object (provided there is no \n in a json value somewhere or in the middle of your json object) and you avoid memory issue as each object is created when needed.
