I'm thinking of iterating through cell in a range and dumping/
documenting the value, formula and other attributes into a database so
that I can sort, filter, analyse cells. Tried range("a1").properties
(i) but properties does not seem to be supported in the object model?

Next, I would like to document properties which are different from
default - is there some approach to define what is default and then
use that as comparison?

I thought of looking at the .xlsx XML file but there's Excel specific
XML to decipher and to use an XML engine rather than the VBA / Excel
Object Model.

Any tips? Or any established tools that already do this?

Thanks.
