Hi @sachinsoni ,
Do you want to parse the JSON data within your app, and then retrieve the address attribute into a collection?
How do you get the JSON data? Using Custom connector?
If you want to parse the JSON data within your app, and then retrieve the address attribute into a collection, I afraid that there is no way to achieve your needs in PowerApps currently.
Currently, within PowerApps, there is no function supported to parse a JSON data. If you would like this feature to be added in PowerApps, please submit an idea to PowerApps Ideas Forum:
https://powerusers.microsoft.com/t5/Power-Apps-Ideas/idb-p/PowerAppsIdeas
As an alternative solution, I think the combination of Power Automate and Power Apps could achieve your needs. You could consider fire a flow from your canvas app, then parse the JSON data (JSON String value) within the flow, then retrieve the desired table value and return back to your canvas app.
I have made a test on my side, please take a try with the following workaround:
Flow's configuration:

Within the "Initialize variable" action, Value field set to following (the JSON String value you mentioned above😞
{"authenticationResultCode":"","brandLogoUri":"","copyright":"","resourceSets":[{"estimatedTotal":1,"resources":[{"__type":"","value":[{"__type":"LocalBusiness","address":{"countryRegion":"Norway","locality":"Oslo","adminDistrict":"Oslo","countryRegionIso2":"Nw","addressLine":"City Road","formattedAddress":"City Road"},"name":"City BT"},{"__type":"LocalBusiness","address":{"countryRegion":"Norway","locality":"Oslo","adminDistrict":"Oslo","countryRegionIso2":"Nw","addressLine":"BT Station Road","formattedAddress":"BT Station Road"},"name":"City Bus"}]}]}],"statusCode":200,"statusDescription":"OK","traceId":""}
Within the "Response" action, Body field set to following expression:
json(variables('JSONString'))?['resourceSets'][0]?['resources'][0]?['value']
The "Response Body JSON Schema" field set to following:
{
"type": "array",
"items": {
"type": "object",
"properties": {
"__type": {
"type": "string"
},
"address": {
"type": "object",
"properties": {
"countryRegion": {
"type": "string"
},
"locality": {
"type": "string"
},
"adminDistrict": {
"type": "string"
},
"countryRegionIso2": {
"type": "string"
},
"addressLine": {
"type": "string"
},
"formattedAddress": {
"type": "string"
}
}
},
"name": {
"type": "string"
}
},
"required": [
"__type",
"address",
"name"
]
}
}
App's configuration:

Firstly, you need to add your above flow connection into your canvas app, then bind it to the "FireFlowToParse" button. Set the OnSelect property of the "FireFlowToParse" button to following:
ClearCollect(ReturnedResult,'PowerApp->Initializevariable,Response'.Run());
Clear(AddressCollection);
ForAll(
ReturnedResult,
Collect(AddressCollection, address)
)
The AddressCollection would be populated with proper records as below:

Please consider take a try with above solution, check if the issue is solved.
If the JSON data you mentioned is from your custom connector, you could consider add the custom connector action in your flow to send HTTP request, then try above solution, returned desired table value back to your canvas app.
Best regards,
