• Xlsx files

  Connect to Excel 2007 (and later) files with the Xlsx file extension. That is the Office Open XML format with macros disabled.

  "HDR=Yes;" indicates that the first row contains columnnames, not data. "HDR=No;" indicates the opposite.

• Treating data as text

  Use this one when you want to treat all data in the file as text, overriding Excels column type "General" to guess what type of data is in the column.
  Provider=Microsoft.ACE.OLEDB.12.0;Data Source=c:\myFolder\myExcel2007file.xlsx;
Extended Properties="Excel 12.0 Xml;HDR=YES;IMEX=1";
  If you want to read the column headers into the result set (using HDR=NO even though there is a header) and the column data is numeric, use IMEX=1 to avoid crash.
  To always use IMEX=1 is a safer way to retrieve data for mixed data columns. Consider the scenario that one Excel file might work fine cause that file's data causes the driver to guess one data type while another file, containing other data, causes the driver to guess another data type. This can cause your app to crash.
