If you have license to use Premium connectors, then you can directly use the Response action to send JSON to PowerApps. This can be collected in a collection using ClearCollect(CollectionName,FowName.Run())
Once you make any changes to the flow, you need to remove it and register it again to the canvas app.
If you do not have license for premium connectors then you can use below expressions:
Clear(MyCollection);With({Loops:(CountRows(Split(Label1.Text,","))/5)-1},ForAll(FirstN([1,2,3,4,5,6,7,8,9,10,11,12,13,14,15],Loops),Collect(MyCollection,{streetNumber:Last(FirstN(Split(Label1.Text,","),Value+5)).Result,streetName:Last(FirstN(Split(Label1.Text,","),Value+6)).Result,Suburb:Last(FirstN(Split(Label1.Text,","),Value+7)).Result,Postcode:Last(FirstN(Split(Label1.Text,","),Value+8)).Result,State:Last(FirstN(Split(Label1.Text,","),Value+9)).Result})))
Note: We cannot pass variable the keys for name of columns in collections, hence this needs to be harcoded. Here, you need to replace Label1.Text with the value that holds this returned string.
Hope this Helps!
