This script was created using the Google Maps application programming interface, available for free from Google Code. SpreadsheetWEB’s scripting support, which can be accessed from the SSW Wizard’s Worksheet Controls, allows you to embed external or self-written HTML scripts into your web applications. This script submits the values in the yellow cells (visible in the Excel spreadsheet image) and generates a map using the maps API. This map is then rendered in the large cell.
The web version can be accessed from here.
