Now open the QIF file that you want to import. Paste the text that you just copied, and replace all of the data up to the date on the first transaction. The entire process should look something like this:
Wondering why you just did that? The data that you just copied is used by Quicken to identify which account the transactions belong to. The original file was missing that critical information, and without it Quicken will have no idea where to put the transactions. In older versions of Quicken it would let you select which account to apply the transactions to, but that doesn’t work anymore. Needless to say it’s an important part of the process if you want to import a QIF file into Quicken.
It may seem like a long process, but once you understand how it works you can probably import a QIF file into Quicken in under 30 seconds. Just save the account information that you copied in Step 3 if you regularly download QIF files from your bank. By saving that information you will never have to go through the export process in Step 2.
