Dear All,

I apologise if this is a simple query, but I am quite new to GIS.
I am trying to convert some UK Ordnance Survey grid references to lat / long, and am having a bit of trouble doing so.
I have found some tables on the web where you can add a value at a time to convert, but ideally I would like to batch convert grid refs. I have come across some macros on other web pages (not ESRI) to do so, but have had some difficulty making these work, and the accuracy of the converted lat/long has not been the best.

I have a converter zip from: http://arcscripts.esri.com/details.asp?dbid=15878. But I haven't managed to make it work with ArcGIS 9.3.

Any suggestions would be most welcome

Thanks in advance
Andrew
