title: Read data from .xls and .ods files
body: <p>Is there a way to read data from excel and open office spreadsheets and save them to a temporary store, like a DataSet or array? I came across ExcelDataReader (http://exceldatareader.codeplex.com/), but it only works if the user has Excel installed on their computer. Some of our users only have Open Office (and others have neither). </p>
