Creating Network Simulation In OMNeT++ Using JSON file -- 2

I have a JSON file that requires utilization for constructing a network simulation in OMNeT++. By means of the JSON file, it is necessary to transform the Network Description (.ned) file and initialization (.ini) file to generate the network. I request your assistance in creating a universal code for converting the JSON file into both .ned and .ini files and making it run Network Simulation in OMNeT++ 6.0.1.
