I was made aware of a free XBRL to spreadsheet converter. You can get to information about that application here.
The application is an Excel spreadsheet with macros. Unfortunately, the macros are password protected so you cannot get at the code. (If you want some code for Excel, I have a lot...send me an email and I can get it to you. I have even more Microsoft Access code should you need that.)
I have not spent much time fiddling with that application so I cannot speak to its utility. Should you find this useful, please let me know. The good thing is that more and more software for XBRL is appearing. I'm optimistic that we should be seeing more and more useful software.
