Export product system to excel

Question

Hi all,

In v1 of openLCA it was possible to export product systems (not the results) to excel. This would output a folder with three files, one of which was the product flows. This was a single sheet with a reduced A matrix of the foreground system.

This is super useful for teaching LCA as I can easily debug a student's model without having them output all of their processes and flows and me spend time digging into each.

Has this feature gone away in v2? If so, please, please bring it back!!

Hi Mik,

a you probably refer to the matrix export - that is still there and with many more options:

you get access to this when a product system is open.

All the best,

Andreas

Thanks for that.

I'm working in dark mode, and that button is grayed out. I never hovered over it to see that it was "Export as matrix!.

Great!!

Actually, now I use this feature, I see that this exports the entire database, which makes it very hard to see the foreground system all in one place.

Is there a way to export in such a way as to see only the foreground system and first tier suppliers?

Maybe I would have to link to system processes, rather than unit processes?

OK, when I work with system processes, e.g. in the ecoinvent LCI database, then I see more like the previous results that I saw.

I'll need to think about how to work with students.
