Try following code to open Excel file:

    String connString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + excelFilePath + ";Extended Properties=Excel 12.0;";
    // Create connection object by using the preceding connection string.
    OleDbConnection objConn = new OleDbConnection(connString);
    // Open connection with the database.
    objConn.Open();
