I thought, I posted code with OLEDB, but now I see that it's missing :-). Maybe I didn't posted it :-)
It works with:

Provider=Microsoft.ACE.OLEDB.12.0;Data Source=c:\myFolder\myExcel2007file.xlsx;Extended Properties="Excel 12.0;HDR=YES";

as connection string
The Extended properties are important :o))
I got this connection string from http://www.connectionstrings.com/?carrier=excel2007
