No sure if this is an acceptable workaround/alternative [0] for Germany but on the "Request My Data" page (https://www.amazon.de/gp/privacycentral/dsar/preview.html) you can request all of your account data and this should include the following file with all of your orders: Retail.OrderHistory.2/Retail.OrderHistory.2.csv

It has the following format: "Marketplace","Order ID","Order Date","Purchase Order Number","Currency","Price","Price Tax","Shipping Charge","Total Discounts","Total Owed","Item Subtotal","Item Subtotal Tax","ASIN","Product Condition","Quantity","Payment Instrument Type","Order Status","Shipment Status","Ship Date","Shipping Option","Shipping Address","Billing Address","Carrier Name & Tracking Number","Product Name","Gift Message","Gift Sender Name","Gift Recipient Contact Details"

(Note: My last export is from January so the filename or format might have changed in the meantime.)

[0]: It provides more data but is annoying / time consuming to use.

I would think Germany would have a standardized digital receipt of transaction in xml that retailers would be required to provide.

Germany is a bit backwards in all sorts of digital areas when you compare it to other european countries.

Except France where it is worse.

I cannot phantom our love for PDFs and physical letters (and cheques). This is maddening when you look at countries such as Estonia or Poland.

UK has a list of my orders dating back to 2002, not as easy data though, just different pages I'd have to scrape
