BTW, there is a new version of LuaCom at:
 http://www.tecgraf.puc-rio.br/~rcerq/luacom/pub/beta2/

I try to use LuaCom to interact with Excel.
Is there some exemple on how to do this ?
Where can I found some documentation about excel COM Objects ?


I do not have examples of LuaCOM with Excel, but you can look up the

I am sending an example of LuaCOM with PowerPoint, it should be
quite similar.
