The WMM Google spreadsheet allows user to calculate declination values for mutiple points. The user may upload a file with location, altitude and date information to this spreadsheet. The user needs only a google account and a browser to use this application and it works on any operating systems.

Behind the Scene

Here's how the program works. The spreadsheet function GetWMM calls a javascript version of the World Magnetic Model. You can see this script by going to Tools -> script editor. You may customize the calculator by tweaking the script. The program runs on Google servers - not on your computer. We have not noticed any daily limit on the calculations - but you might hit a limit if you calculate millions of points per day!
