Is there a quick way to add multiple new products?

[Nocturnaloner]

I have a client who wants to update inventory frequently, but is technically challenged, and uncomfortable with using spreadsheets. I have Easypopulate installed, but he won't use it. What he wants is a way to add or update multiple products quickly, with a simple table layout, like the Quick Price Updates contribution. It's good, but I still need to be able to add multiple new products, and upload their pictures all at once. Does such a contrib exist, or does anyone have suggestions on how to hack these features into Quick Updates?
