From NSX-v version 6.4.0, NSX API begins to support JSON format for its response not like before only XML format. From my own expereince, I prefer to use JSON format than XML format as it is easier to decode and encode JSON data than XML data. So I took 1 weekend to re-write my old Python code. Now this code can get Json format NSX-V DFW rules from NSX manager and then place into a CSV file so that you can view and search your DFW rules easily.
Below is a sample of CSV file which is generated by my Python code.
I have put the source code in Github:

Feel free to enjoy.
