Hello,
I am from Germany and of´course German is my native language;) and I work as an Fraud&Compliance for one of Acquiring banks in Germany, know a lot about banking and banks in general.
I can easily do the disired task..I have just tried out to search online for few data from the spreadsheet you provided and could find esily what was needed. Apart from that, should there be a problem with one or the other bank, I have an access to some services where I can retrieve the required data on banks.
Best Ragards,
Silwia
