You can get the Latitudes and Longitudes by using sample script like below, in this we are getting the coordinates by sending city to Google.
(biff, embedded labels, table is [Sheet1$]);
let noRows = NoOfRows('CustomerTable')-1;
for i=0 to $(noRows)
let a = peek('Customer',$(i),'CustomerTable');
let b = peek('City',$(i),'CustomerTable');
let c = peek('Quantity',$(i),'CustomerTable');
'$(a)' as CustomerName,
'$(b)' as CustomerCity,
'$(c)' as CustomerQuantity,
([result/geometry/location/lat]) as latitude,
([result/geometry/location/lng]) as longitude
FROM [http://maps.googleapis.com/maps/api/geocode/xml?address=$(b)&sensor=false] (XmlSimple, Table is [GeocodeResponse]);
