Grab Response Groovy Scripting SoapUI

Hi Team,

I am new to Soap UI and Groovy

I want to grab all the pin codes under formatted_address from the below Rest url:

https://maps.googleapis.com/maps/api/place/textsearch/json?query=restaurants+in+Kolkata&key=AIzaSyBadoqpOCBQzhrcoYSTQf7hKMTyewq3fd0

And Place all the grabbed pin codes in Excel Sheet

Would Regex help? or loops should do?

Can you help me to find a way to resolve it.

Thankyou
