SSIS Excel column datatype problem Ver2.0:

I have come across another similar situation today when using one of the excel file received couple days back. turns out the 'quantity' column has numbers and strings like (5,10, "100+"). Problem with this is during the validation of the package, "100+" are discarded by the package and returned to me as "Null" values.
In this case unfortunately only thing I could do is parse the whole sheet in as one column and then write script to differentiate columns.
