Hi,

SplitJson processor accept as an input Json array of objects.

How to split json array into individual records using SplitJson processor?

Where can I check examples of "JsonPath Expression" for "SplitJson processor"

I checked documentation for "SplitJson"- but it not covers JsonPath Expressions.

Thanks.

If it is a flat structure you probably want : $.*
Or, if it is some part of a nested structure: $.firstpart.secondpart.*

@dchaffey Hi After Array split I get 12 flowfiles, Now I want those flowfiles to use one by one, means when 1 flowfile will execute its complete process then only next flowfile should be sent ahead. I tried using wait and notify but didnt worked properly. Can you suggest something

I'm receiving an array of the Json objects like [{"key1":"value1", "key2":"value2"},{...},{...}], all what I'm doing is using SplitJson with the following expression.

If you have another structure of a Json your expression could be different, or you should use any transform(f.e. JoltTransform) at first.
