Ankita Das Refer ecoinvent method files and take the characterization factors for the impacts e.g. acidification, marine eutrophication or any other and use the same in your excel formulas to calulate the mid/end point impacts.

Alternatively, if any of your links have SimaPro then you can take the CFs from software as well.

Hope it helps!

You will also see my detailed answer in it.

I would recomend you to use OpenLCA is a freeware software ( http://www.openlca.org/) and the EcoInvent database should be also freeware on your country ( https://www.ecoinvent.org/database/buy-a-licence/price-list/price-list.html). Excell based approaches are prone to errors and you get more reliable results wiht specialized software avaliable.

Thank you for your valuable comments.
