yes, I'm still interested in that. We talked about marking cells with 
something like little square in a corner...

and I think we could have simply a list of "suspicious" cells, that will 
collect results of different checks. With some description or check type 
indication we will be able to undertake different actions for each cell 
in the list. Beside a cell indication we could have some information on 
the status bar saying what's wrong with the cell and maybe an element in 
a context menu, e.g. "Fix cell(s)->", which will let user to convert 
string to number/change unit to be consistent with the rest/.../even fix 
typo in formula name (e.g. "SU" to "SUM/SUMPRODUCT/SUMSQ").

Where can I start? You showed me some code during the Hackfest, but I 
don't remember what it was exactly. Is ScOutputData::LayoutStrings in 
sc/source/ui/view/output2.cxx the right place?
