I've got a list of geographical locations in an Excel spreadsheet. I want users to be able to search for a user-defined location, and then have the X number of closest locations from the list pulled up and displayed, sorted by nearest to farthest by travel time via car. I know Excel alone obviously can't do this.
I have minimal/no programming knowledge. Just an Excel tinkerer. I figure that, at a minimum, this would require utilization of a mapping service like Google Maps or Mapquest.
