How to Connect XLSX file (Excel Workbook) through ADO

Using Excel (Xlsx) file as a database using VBA (ActiveX Data Objects - ADO)

In the past we have already seen how to Connect to an Excel file using ADO and query its contents. That was using Microsoft Excel 2003 or earlier. With Office 2007 the file formats haver changed to XLSX, which might create the following problems

to solve that use the following Connection string:

cN.ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Users\comp\documents\visual studio 2010\Projects\ExcelWorkbookDocLevel\ExcelWorkbookDocLevel\ExcelWorkbook1.xlsx;Extended Properties=Excel 12.0;Persist Security Info=False"

    This worked for the 2007 Excel xlsx format, but not the 2010 or higher format, do you know of a way to read from these higher versions of Excel?
