CSV to QFX Converter for Quicken with QIF and IIF Files from Bank CSV and PDF

Can you convert CSV to QFX?

Yes. A QFX file is a text file in the Open Financial Exchange layout with a few Intuit tags added, so any tool that can read the CSV columns correctly can write one. The work is in the reading. A converter has to decide which column is the posting date, whether the amount is one signed number or a debit and credit pair, which text is the payee, and how to give every line an ID that stays the same the next time you export. BankXLSX does that on upload and shows you the rows before you download anything, which is where most bad imports are caught.

If you are curious what is inside the result, the QFX file format page walks through the header, the INTU.BID tag and each transaction field.

Which file should you download for your software

The upload is the same every time. What changes is the download you pick. This table follows what each vendor documents, with the one caveat that matters for Quicken users spelled out.

QFX or QIF for Quicken

Use QFX unless you have a reason not to. Quicken treats a QFX file like a download from the bank: it shows the transactions for review, matches them against what is already in the register, and ignores the ones it has seen. That is the behavior you want when you import every month.

QIF is older and looser. It carries a date, an amount, a payee and a memo, and nothing that identifies a transaction, so Quicken cannot tell a second import from a first one. There is also a documentation conflict you should know about. Quicken support still has an article stating that QIF import is not available for checking, savings or credit card accounts, while newer Quicken documentation says those limits no longer apply. In practice current Quicken Classic versions accept it, but if your copy refuses a QIF into a bank account, that article is the reason, and the QFX download is the way around it. The bank statement to QIF converter page covers the QIF route in more detail.

What the converter does with a messy CSV

Bank exports are not tidy. These are the cases that break simple converters, and what happens to each one here.

If a file cannot be read, you get an error that says so instead of a QFX with half the lines missing. When that happens, the statement PDF for the same period is usually the cleaner source.

When the bank gives you a PDF and no CSV

This is the more common situation for older months. Online banking keeps downloadable activity for a limited window, while statements stay in the archive for years. Upload the PDF to the same converter and you get the same downloads. Scanned statements and phone photos are read with OCR.

If the destination is QuickBooks Desktop, the bank statement to IIF converter page explains when IIF beats QBO.

CSV to QFX converter pricing compared

There are two established desktop tools for this job and they are cheaper than BankXLSX for one person converting CSV files on one computer. That is worth saying plainly. BankXLSX costs more because it also reads PDF statements and scans, and because a plan covers the whole team.

ProperConvert prices were read from the ProperSoft purchase page in October 2026, which also lists a 14 day money back guarantee on the first order. MoneyThumb describes its license types on the CSV2QFX help page without dollar amounts, so check its store for the current figure. For a closer look at each vendor see the ProperSoft alternative and MoneyThumb alternative comparisons, and bank statement converter pricing for our own plans. If QIF is the file you need, the CSV to QIF converter software comparison covers that choice.

Why does Quicken reject a converted QFX file?

Almost always because of the institution ID. Quicken reads the Intuit tag in the file and checks it online, and when the ID is missing or not one it recognizes you see a message that Quicken is unable to verify the financial institution information for this download. Files from BankXLSX carry a recognized Web Connect institution ID for that reason. Two other causes are worth ruling out. The account may still have online services switched on for a direct connection, which can block a Web Connect import into the same account. And the account type in the file has to agree with the register you import into: a credit card file will not go into a checking account.

We have not tested the output against every Quicken release, so import one month into a backed up data file before you run a full year. If Quicken refuses the file, contact us and send the message it shows.
