I have a spreadsheet that contains address data (among others) and which the customers want to be able to display on his website as a Google Maps.
Implementation of a Google Map using a Google Spreadsheet as data source is well documented. However in this particular case the customer wants to keep the spreadsheet private - i.e. nobody should see the raw data, only the map.
Is something like this possible?
(Note that the map is either to be embedded in a Google Site or on a public website running whatever software - i.e. no option to use php, etc)
