Compare 2 files for BOM

[Jaco van der Molen]

I have this big model of 12000+ bricks I am working on.
Somewhere on the way, I lost some work :-( and had to redo a few things here and there.
Before the loss of work, however, the model was 99% complete and I was able to restore the lost file and thus its BOM.
Finishing the model, there are some changes and additions here and there and I kind of lost what bricks went missing, got replaced, and are not used anymore.

So, my question: Is there a clever way to compare 2 files to see the difference in the BOM?

OK, so LDInspector can do this perfectly.

@Stefan: can you export a partslist to Excel, or some CSV format (or any other list BL wishlist for example)?
