Amazon Japan Order History Downloader

This extension allows downloading order history details from Amazon Japan (amazon.co.jp) in a structured file format, which is useful for the purpose of keeping track of personal spending and finance.

It fetches order details for all orders on the currently selected page in Order History ("注文履歴").

If you have more than one page of Order History, you can open each page as needed and run it. Finally, all fetched orders can be downloaded as one consolidated file.

The export file is in pipe-delimited format with these fields: Order ID, Order Date, Item name, Price. Items are sorted by Order Date.
(Note that while file extension is ".csv", pipe delimiter is used to avoid being mixed up with any commas in the item name)

Limitations
- The display language on Amazon Japan must be in Japanese.
- After downloading orders on a page, please double-check the "Fetched orders" count. A full page should normally have 10 orders, so it should be fairly obvious if something is missed. (While the extension is tested to be working as of the release date, Amazon Japan occasionally changes its page layout in subtle ways, which would cause this extension to break. A fix is necessary in such case.)

Release Notes

2.0
- Major update to the extraction logic, which is now working as of 2026-01-04. Previous version of this extension no longer works - some time in 2025 there were significant changes in the Amazon Japan's invoice web page code which broke this.
- Can handle digital order items (e.g. e-book) now, which was not supported previously.
- Enhanced fetch display status, showing more details about current page fetch results, making it easier to reconcile whether the fetch is working properly (e.g. 10 orders fetched).

1.1
- Fixed issue where some orders were missed and some had errors due to failing to find the order date, It appears there were some changes to Amazon Japan's page layout recently.
