Hi

I have a Json I/P which looks like:

```
{
	"data": { 
		"arrayField" :[{"id" : 7,"data" : "a"},{"id" : 3,"data" : "b"}],
		"field1" : "value1"	
	}
}

```

Where arrayField can contain any number of element.

I want to access the arrayField inside elasticsearch script which needs a format like `{["id" : 7,"data" : "a"],["id" : 3,"data" : "b"]}.`

How can I do this conversion ?

Hello,

you can use split filter,  
Ex:-  
filter {  
split {  
field =\> "arrayField"  
}  
}
