The problem with jet, is you still have to install the data provider for it (though this is also free) or have office installed for it to work. If you simply need to read an excel file there are plenty of fully managed libs out there that will do the track just fine without the need to install anything.

I've listed a few here. I have used excelreader plenty with good results.

Excel reader seem to be light on the documentation side of things. so here is an example of how to use it

IExcelDataReader reader = null;
try
{
    using (FileStream stream = new FileStream(ofd.FileName, FileMode.Open))
    {
        string ext = System.IO.Path.GetExtension(ofd.FileName).Replace(".", "").ToUpper();
        if (ext == "XLS")
            reader = ExcelReaderFactory.CreateBinaryReader(stream);
        else
            reader = ExcelReaderFactory.CreateOpenXmlReader(stream);

        reader.IsFirstRowAsColumnNames = true;
        using (DataSet ds = reader.AsDataSet())
        {
            foreach (DataRow dr in ds.Tables[0].Rows)
            {
                ImportData toAdd = new ImportData()
                    {
                        Format = dr[0].ToString(),
                    };

                Database.Datastore.InsertObject(toAdd);
            }
        }
    }
}
