Hi @aditya_gupta41
If I understand you just need the value of the key "ntgr" if its 'xyz' ?
Then I would recommend that you get a filter snap and put expression enabled inside the snap and drag and drop the path until 'ntgr' and put next to it : == 'xyz'.
So after the expression you only get the result with that value and you could put a mapper snap next to it to only get that value.
Another option to acquire this is to use mapper snap and drag and drop the path until 'ntgr' and type next to it : == 'xyz' ? $theValue : null
and as target path the name how you want: for example $value
This will show in the result: $value: 'xyz' or if it's not 'xyz' , $value: null
Hope this helps
Jens
