This spreadsheet, which consisted of years of purchases and thousands of dollars of receipts, was easy to compile within the Amazon account interface, and it fit nicely into that day's chatter about other companies' issues with data privacy and GDPR compliance. So, for funsies, a bunch of us reviewed our past decade-plus Amazon existence by grabbing a giant spreadsheet from our individual "order history" pages.
