Connect to Excel 2007 (and later) files with the Xlsx file extension. That is the Office Open XML format with macros disabled.
例如:
Provider=Microsoft.ACE.OLEDB.12.0;Data Source=c:\myFolder\myExcel2007file.xlsx; Extended Properties="Excel 12.0 Xml;HDR=YES";
"HDR=Yes;" indicates that the first row contains columnnames, not data. "HDR=No;" indicates the opposite.
