Geocoding from Excel: Yahoo -vs- Bing -vs- Google

I have already looked at geocoding with Bing Maps -vs- Google Maps and Google Maps is a clear winner. Yahoo Placemaker is pretty good at first glance even though it claims not to be a geocoder. Note that I am just using the basic REST URI query in all these examples – since the whole point to access directly from Excel. Comparing capabilities under Javascript would be a whole different ballgame.
  • Yahoo require you to get a Key to use Placemaker which they call and Application ID. In this downloadable example, I am using my key. If you use this code for anything, please get your own and follow the Yahoo rules on usage. Google do not require you to get a key, but limit your usage to a small number of queries daily.
  • Yahoo was as good as or better than Google in dealing with ambiguity.
  • The Yahoo response is clean and does not contain a bunch of unnecessary waffle.
  • The Yahoo response is even simpler than the Bing one, and easier to deal with and decode. It is so similar to Bing that I was able to use the same modules to deal with both, so implementing Placeholder was about a 30 minute job, mainly to find out what the field names were.
  • Yahoo provides less detail than both Google and Bing, but most of what you would need is there. It does not provide a ‘cleaned up, full address’ field though, which the other 2 do. On the other hand, this can easily be constructed from other fields.
  • Its confusing that Yahoo Placeholder is not actually Yahoo Maps. Yahoo Maps is actually OVI maps, which I haven’t tried .. yet.

I am a Google Developer Expert and decided to investigate Google Apps Script in my spare time. The more I investigated the more content I created so this site is extremely rich. Now, in 2019, a lot of things have disappeared or don’t work anymore due to Google having retired some stuff. I am however leaving things as is and where I came across some deprecated stuff, I have indicated it. I decided to write a book about it and to also create videos to teach developers who want to learn Google Apps Script. If you find the material contained in this site useful, you can support me by buying my books and or videos.
