Need to Store the Protocol Heirarchy, Endpoint statistics, Conversation statistics, and http statistics in Json format using Tshark

edit

I am using Wireshark for capturing the packers and Tshark for analysis purposes. When I am trying to store the Protocol Hierarchy, Endpoint statistics, Conversation statistics, and HTTP statistics result in JSON format using Tshark, I am not getting the output as I expected it to be but just a text file which I do not want. Could someone please help me to find a way out for this? I have attached the output I am getting after using the command sudo tshark -n -q -r dump.pcap -z io,phs > fff.json
