I have uploaded two improved tools for viewing SEC filer company taxonomies. Both tools are written using Microsoft Excel 2003. These tools can be found here:
The next tool on the list to create is a tool which allows you to compare a company taxonomy with the US GAAP Taxonomy. Although, I will only do this for the Commercial and Industrial entry point.
I would challenge people to understand how to write Excel macros to improve these applications (i.e. add new interesting features) and send them to me and I will make them available to others.
