How can I download my purchase history to a file?

Hi

I know how to see my purchase history in iTunes but since the dates and charges on this screen are DIFFERENT from those actually end up being charged to my credit card and I need to investigate quite a few unauthorized subscriptions I wanted to download the history to an Excel file.

I can not even select or copy text from this iTunes screen so the option of copy-paste is also unavailable.

I hate to start typing it - as I said it's many transactions.

Any suggestion is welcome.
