How to parse array of arrays inside json

Thanks for the reply

My json structure is dynamic i.e key names and values names will always change. I dont have any fixed json structure

If I store in same document then it will be difficult for me to visualize the data because it contains different names for different records so I need to store them in seperate records with same name which I will achieve by aliasing

It would be helpful if I get a proper solution to achieve this as I am new to logstash

Thanks in advance
