For Amazon Japan, under "Ordering and shopping preferences," I couldn't find a "Download order reports" option. I contacted Amazon Japan support and alas, .CSV export functionality is available for the USA but not Japan
A workaround that I figured out was to view my 2020 order history as a web page and use an app to capture to PDF. I'm on a Mac and my PDF capture tool of choice is Paparazzi! 10 webpage captures versus manually downloading 100 PDF invoices one by one. Sounds like a win in my book.
I began writing this post out of frustration, but then once I figured out a workaround, thought that I would share. Also, am interested if others have encountered this problem, and what efficient solutions you've figured out? Thank you.
