Maybe you need to be more specific?
But afterthought, I guess you mean the eco platform, https://www.eco-platform.org/epd-data.html. There, the "xml" is ILCD, and the csv is a simple table. The simple table cannot be imported, and ILCD can maybe be imported into openLCA but I did no test it.
Maybe you can try and report back?
Thanks a lot, best wishes, Andreas
edit after the comment (thank you for it):
Indeed, downloading one arbitrary example
retrieves a very small ILCD archive with a funny name as well:
which has only one flow
So this seems to be on the eco passport side.
