In a way that's what I meant, if I understand correctly. (which I'm not entirely sure that I do.)
My thoughts were this. If you already have at least one category that is a sub-category (preferably "manually" generated groups), then export of product (active or all) for that category (or sub-category) using the dropdowns across the top of the EP4 tools/admin screen would reflect the information/way that EP4 would expect the data to be made available to reproduce the same type/style of a product.
Mind you, again, the file generated is UTF-8 and the file normally expected for upload followed by import should also be in UTF-8 format. Further, the expectation is that if you look at the raw csv file using a plain text editor both before and after editing, they should look relatively similar. EP4 does add some extra double quotes (" not ') around information, that at least when using Open Office tend not to be "put back", but that's not necessarily an issue.
Anyways, I don't want to overload, especially if the first couple of things above address the issue (again, assuming I understand correctly)
