Hi Neeta,

If you hover your mouse over one of the highlighted entries, you will see some options appear one of which lets you copy the path to the object.

With that in hand, you can, if you need to walk through the array, replace any array references with a looping function.

```auto
msg.payload.sensordatavalues.forEach( (val) => {
    // val.value and val.value_type are what you need
})

```

You can also loop through the array using a split node.  
e.g.

```auto
[{"id":"354197ee.e1a278","type":"inject","z":"bf9e1e33.030598","name":"","props":[{"p":"payload.sensor_data_values","v":"[{\"value\":\"2:20\",\"data_type\":\"f1\",\"id\":1234},{\"value\":\"3:20\",\"data_type\":\"f2\",\"id\":1235}]","vt":"json"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","x":100,"y":80,"wires":[["fa34fe67.be89c","208ed9c4.f23cce"]]},{"id":"fa34fe67.be89c","type":"debug","z":"bf9e1e33.030598","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"true","x":430,"y":80,"wires":[]},{"id":"208ed9c4.f23cce","type":"change","z":"bf9e1e33.030598","name":"","rules":[{"t":"move","p":"payload.sensor_data_values","pt":"msg","to":"payload","tot":"msg"}],"action":"","property":"","from":"","to":"","reg":false,"x":350,"y":120,"wires":[["f49a9fd5.5aa04"]]},{"id":"f49a9fd5.5aa04","type":"split","z":"bf9e1e33.030598","name":"","splt":"\\n","spltType":"str","arraySplt":1,"arraySpltType":"len","stream":false,"addname":"","x":630,"y":120,"wires":[["c800f9d1.d02bf8"]]},{"id":"c800f9d1.d02bf8","type":"debug","z":"bf9e1e33.030598","name":"do something to each array element","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"payload","targetType":"msg","statusVal":"","statusType":"auto","x":880,"y":120,"wires":[]}]
