Function GetCoordinates(Address As String) As String

    '-----------------------------------------------------------------------------------------------------
    'This function returns the latitude and longitude of a given address using the Google Geocoding API.
    'The function uses the "simplest" form of Google Geocoding API (sending only the address parameter),
    'so, optional parameters such as bounds, key, language, region and components are NOT used.
    'In case of multiple results (for example two cities sharing the same name), the function
    'returns the FIRST OCCURRENCE, so be careful in the input address (tip: use the city name and the
    'postal code if they are available).

    'NOTE: As Google points out, the use of the Google Geocoding API is subject to a limit of 2500
    'requests per day, so be careful not to exceed this limit.
    'For more info check: https://developers.google.com/maps/documentation/geocoding

    'In order to use this function you must enable the XML, v3.0 library from VBA editor:
    'Go to Tools -> References -> check the Microsoft XML, v3.0.
