Google App Script - Trouble Outputting and Parsing Data - json

Question

I'm using a google app script to pull data in regards to our chrome book devices, all is working ok apart from when trying to interrogate the "cpuStatusReports"
If i use
cputemp = JSON.stringify(chromebooks[i].cpuStatusReports)
Logger.log(cputemp);
the output i get is this
[{"cpuUtilizationPercentageInfo":[23,16,12,18,15,12,18,15,20,16],"cpuTemperatureInfo":[{"temperature":43,"label":"soc_dts0\n"},{"temperature":43,"label":"soc_dts1\n"}],"reportTime":"2019-06-24T11:53:24.973Z"},{"cpuUtilizationPercentageInfo":[45],"cpuTemperatureInfo":[{"temperature":33,"label":"soc_dts0\n"},{"temperature":34,"label":"soc_dts1\n"}],"reportTime":"2019-06-25T12:43:40.826Z"},{"cpuUtilizationPercentageInfo":[12],"cpuTemperatureInfo":[{"temperature":42,"label":"soc_dts0\n"},{"temperature":42,"label":"soc_dts1\n"}],"reportTime":"2019-06-25T14:01:47.016Z"},{"cpuUtilizationPercentageInfo":[27],"cpuTemperatureInfo":[{"temperature":29,"label":"soc_dts0\n"},{"temperature":30,"label":"soc_dts1\n"}],"reportTime":"2019-06-26T07:59:40.739Z"},{"cpuUtilizationPercentageInfo":[12,12,7,8,3,4,14,13,27,12],"cpuTemperatureInfo":[{"temperature":45,"label":"soc_dts0\n"},{"temperature":46,"label":"soc_dts1\n"}],"reportTime":"2019-06-26T10:59:41.370Z"}]
How can i split this? in particular im after the "cpuTemperatureInfo" field?
If someone could provide a working example i can then use this for the Diskreport as well as this is also outputting in the same format.
Thankyou for your help!

Try this:
cputemp =(chromebooks[i].cpuStatusReports).toString().split(",");
Logger.log(cputemp);
for (var j in cputemp)
{
var element = cputemp[j];
Logger.log(element);
}
You can see then which j has the entry you need
