I use this to extract my Ebay purchase history to a spreadsheet. As Ebay does not allow research of older purchase history (beyond 2 years), I find maintaining my own archive very useful. Additionally, once the data is in a spreadsheet, its much faster to look up more recent purchases than dealing with Ebay's clunky interface for anything that isn't on the first page of Purchase History. This add-on isn't perfect, but it is much better than anything Ebay offers.

UPDATE 1/2/2020: It looks like Ebay has done something like move the "Purchase Date" column, as that no longer populates in this Ebay Report add-on. However, it did work in May 2019, but I'm not sure when in between Ebay broke this add-on. I'd love to get that "Purchase Date" field working if possible.

This module is very good, but I can't set separator for csv export because tab separator is not well for me...
