I live in Germany and have a German €-denominated credit card. I used to download my monthly transactions in CSV format, but after a recent web site redesign, the new credit card web site only allows downloads as PDF.
I contacted the bank about this, and they replied that German law requires them to give the transactions in a read-only format such as PDF.
I don't know what law they're referring to, but this seems far-fetched to me. I could see a law requiring them to make statements available in a read-only format, but I find it hard to believe that the law would insist that exclusively read-only format is permitted.
Would anyone be able to locate the law in question, so I can read it for myself? (I can read German reasonably well.) Articles about this law or other commentary would be welcome as well, in English or German.
