    If you are reading only xls files then use Microsoft.Jet.OLEDB.4.0 that is inbuilt with your .net framework.

    If you are reading xlsx files then use Microsoft.ACE.OLEDB.12.0. The drivers for this can be download freely from Microsoft site. You don’t need to install Microsoft officer for interoping.

    Use following connection string

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

    Download drivers from here

    Refer this for running example
