I am not very clear about you question but I would suggest if you are talking about analysis then you can try XLSTAT either basic or ECOLOGY for the same which works as an excel Add in

Best of luck

You can try OpenLCA which is available here http://www.openlca.org/

You can export the results to excel. OpenLCA also provide the databases (free and paid), but you can always use your own data.
