I use NLB (Nova Ljubljanska Banka) and I wanted to import data to Quicken.
The problem was, that NLB only supports QIF or CVS export and Quicken only supports limited QIF import.
When I looked more deeply I found out that the problem occurs because of the date format. NLB exports date as DD.MM.YYYY andQuicken expects date to be MM/DD/YYYY.
This can easily be achieved with search and replace functionality built in almost every text editor. I use a free Notepadd++.
Open qif file in your editor, go to search and choose Regular expression mode. You can find all occurrences of a date with expressionD(.*).(.*).(.*) and replace it with expression D2\1\3
Let me know if I helped 😉
