This is only marginally Excel related, but it entertained me for several minutes. Batch Geocode allows you to upload addresses and it maps them and provides meta data that you can copy into the application of your choice.
I downloaded their Excel template and entered all the addresses for the Western Nebraska golf courses I played a couple of years ago. It produced a map of my very own and a web page to put it on. As long as someone visits that site once a month, it will remain live. I predict that it will get no less than five hits in the next day or so and that will be it.
I have no idea what I would use this for, beyond my own amusement, but I always appreciate apps like this. It does what it says it’s going to do and there was absolutely no hassle getting it to work. Copy, paste, click a few buttons and it’s done.
