            //Create Connection to Excel work book
            OleDbConnection excelConnection = new OleDbConnection(excelConnectionString);

Since you are making us guess at which error you are seeing, my guess is that excelConnectionString is wrong.

I think you have specified an incorrect Provider for your excel connectionstring.

Excel connections are usually made use an ACE or JET provider.

Try changing your connectionstring to something like:

C#

string excelConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + path + ";Extended Properties=Excel 8.0";

or

C#

string excelConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + path + ";Extended Properties=Excel 8.0;";

Hope it helps.

Hi,

String strExcelConn = "Provider=Microsoft.ACE.OLEDB.12.0;" +
"Data Source=" + Server.MapPath("your .xlsx file path;") + ";"
+ "Extended Properties='Excel 12.0;HDR=Yes'";

Good Luck
