Exporting data to online form and retreiving results for display

Is it possible to enter data into cells in a worksheet, then - use the data from those cells to fill fields in an online form AND import the results from said online form to display back within excel? Example - I would like to enter address and zip code data into excel and have it display the decimal longitude and latitude of that site. There are several tools online i have found that perform this function. I just do not know how to make it work strictly within excel if it is even possible. Any help is very much appreciated.

I can't vouch for this myself as I've not looked at it but this would appear to utilise the Geocode function as offered via the Google Maps API:
