Here is my array json.  
"service\_lines": [  
{  
"id": 584942,  
"is\_approved": null,  
"aar": {  
"category": {  
"id": 42,  
"name": "Tires"  
},  
"system": {  
"id": 1,  
"name": "Tire"  
},  
"subsystem": {  
"id": 1,  
"name": "Tire"  
},  
"service": {  
"id": 53,  
"name": "Service Call - Tire"  
}  
},  
"vmrs": null  
}  
]  
These array type json is inside a nested json and I'm getting this data dynamically. Like sometimes i may get 4-5 arrays or even upto 10. I tried splitting the field, but nothing works well. Is there any way I can parse the data?  
Any suggestion is appreciated. Thanks much.

A json filter will parse arrays inside JSON objects. What do you not like about the result?
