hi guys,

how to do one to one mapping of below two lines - number of comma separated values in message and header fields can be dynamic but number of items in both fields will be same

```
 "message" => "error_count,10,20,30,50,60,70,80,90,110,110",

    "header" => "name,pl-3,pl-4,pl-5,pl-6,pl-7,pl-8,pl-9,pl-10,pl-1,pl-2"

```

ouput needed

name =\> error\_count  
pl-3 ==\>10  
pl-4==\>20
