Hi,

Could someone advice me how to access JSON-data in deeper levels, for example street and area in this example data. I'm able to read upper level like location and formatted_address but how to access child data of address_components?

{

"results": [

{

"location": "POINT (24.937573 60.160291)",

"address_components": {

"street": "Merimiehenkatu",

"area": "Uusimaa",

"country": "Finland",

"street_nbr": "29",

"post_office": "Helsinki",

"postal_code": "00150",

"country_code": "FI"

},

"formatted_address": "Merimiehenkatu 29, Helsinki, 00150 Uusimaa, Finland",

"location_type": "POINT"

},

{

"location": "POINT (-79.906981 42.991202)",

"address_components": {

"street": "Fourth Line",

"area": "Ontario",

"country": "Canada",

"street_nbr": "00150",

"post_office": "Byng",

"postal_code": "N3W 2G2",

"country_code": "CA"

},

"formatted_address": "00150 Fourth Line, Byng, Ontario N3W 2G2, Canada",

"location_type": "POINT"

},

{

"location": "POINT (21.483384 61.140578)",

"address_components": {

"street": "Merimiehenkatu",

"area": "Satakunta",

"country": "Finland",

"street_nbr": "29",

"post_office": "Rauma",

"postal_code": "26100",

"country_code": "FI"

},

"formatted_address": "Merimiehenkatu 29, Rauma, 26100 Satakunta, Finland",

"location_type": "POINT"

},

{

"location": "POINT (22.954244 59.836179)",

"address_components": {

"street": "Merimiehenkatu",

"area": "Uusimaa",

"country": "Finland",

"street_nbr": "29",

"post_office": "Hanko",

"postal_code": "10900",

"country_code": "FI"

},

"formatted_address": "Merimiehenkatu 29, Hanko, 10900 Uusimaa, Finland",

"location_type": "POINT"

},

{

"location": "POINT (21.401145 60.802559)",

"address_components": {

"street": "Merimiehenkatu",

"area": "Varsinais-Suomi",

"country": "Finland",

"street_nbr": "29",

"post_office": "Uusikaupunki",

"postal_code": "23500",

"country_code": "FI"

},

"formatted_address": "Merimiehenkatu 29, Uusikaupunki, 23500 Varsinais-Suomi, Finland",

"location_type": "POINT"

}

]

}
