In case you get the strings on separate rows for every entry, like
{"licenseexpdate":"","licensenumber":"ysdksnjdk l", "state":"Pennsylvania"}
{"licenseexpdate":"08/12/2020","licensenumber":"lic1235","state":"Florida"}
{"licenseexpdate":"","licensenumber":"gsdgfsef" ," state":"South carolina"}
then this formula will do:
Code:
=MID(A2,FIND("state",A2)+8,FIND("}",A2)-FIND("state",A2)-9)
