It provides quite a good interface to manipulating excel files and I 
find it pretty easy even for my entry level!

In my case there's no such risk of manipulating the excel file. I'm in 
charge of it! :-) Sure it might at a later stage be misused and messed 
up inadvertedly, but we're just trying to validate an idea, i.e. writing 
specs without using any word processor.

I'm trying to bypass the need to go through a mark up language (to a 
certain point), in order to facilitate the transition from an 
unstructured approach to document writing to a more structured one.

I would have proposed SGML or XML and style sheets but unfortunately is 
hard to move from M$Word to XML (OMG I need to write code?!?!!). So to 
facilitate the transition to a structured approach I've come up with the 
idea to go through an automatic generation of documents using excel as a 
UI.

In a later stage with could move onto a full-fledged database and have 
simpler web access, but using the same backend for generating documents 
(i.e. some parser and latex).

Sure, there are corner cases that might mess up the whole structure, 
which at the moment is not too fool proof, but I'm trying to test the 
idea and see what I can come up with. Once the flow is in place I could 
think over some more reliable approach as an interface to a database.

I've never understood people discarding newsgroups in favor of more 
'recent' technologies like social networks. Long live the USENET!
