Excel Geocoder

17 Apr

ESRI makes maps for Office. I thought this could be interesting and went to work on trying to insert a map in to a spreadsheet. I did not have much luck. Instead, I decided to throw together a quick macro that would geocode addresses in a spreadsheet and give back coordinates. I do not think VB Script can parse JSON, so the result is ugly, but you get the idea.

Start with a spreadsheet of addresses

sheet

 

Then create a Macro – I copied the code for reading the URL from Ryan Farley.

Sub Macro1()
Range(“A2”).Select
i = 2

Do Until IsEmpty(ActiveCell)

URL = “http://coagisweb.cabq.gov/arcgis/rest/services/locators/CABQ_NetCurr/GeocodeServer/findAddressCandidates?f=json&outSR=4326&street=” & ActiveCell.Value
Dim objHttp
Set objHttp = CreateObject(“Msxml2.ServerXMLHTTP”)
objHttp.Open “GET”, URL, False
objHttp.Send
Cells(i, 2).Value = objHttp.ResponseText
i = i + 1
ActiveCell.Offset(1, 0).Select
Set objHttp = Nothing
Loop

End Sub

The code starts at cell A2 and reads addresses until it reaches an empty cell. It takes the value and sends it to the ESRI REST endpoint for the City of Albuquerque Geocoding Service. It sets the cell next to it with the results. They should really be parsed, but I am too lazy and was just curious if it could be done. It can. The result is below.

I am still thinking of how to embed a web page in the sheet.
