OFX vs QFX vs QBO: What Is the Difference?

Anyone comparing OFX vs QFX vs QBO is usually staring at a downloaded file and a piece of accounting software that refuses to accept it. The three formats look almost identical inside, which makes the confusion understandable, but they are aimed at different tools. This guide explains how they relate, what sets each one apart, which software reads which, and how to convert between them so your bank data imports cleanly.

The one thing they have in common

All three formats are built on OFX, the Open Financial Exchange standard. OFX defines an SGML structure for carrying financial transactions: dates, amounts, types, descriptions, and unique identifiers, wrapped in tagged fields. QFX and QBO both start from that same structure. So at the data level, an OFX, a QFX, and a QBO holding the same statement look very similar. The differences are in the details that tell software which file is meant for it.

OFX: the open standard

OFX is the base format and the only one of the three that is vendor-neutral. It is read by a wide range of accounting and budgeting tools, including Xero and GnuCash. Because it is not tied to a single company, OFX is the safest target when you are unsure what your software wants. There is more detail in the dedicated guide on what an OFX file is.

QFX: OFX for Quicken

QFX is Quicken's Web Connect format. It is OFX with extra identifiers that Quicken uses, including a financial institution identifier that ties the file to a recognized bank. Quicken expects a QFX rather than a plain OFX, which is why a generic OFX sometimes fails to import there.

QBO: OFX for QuickBooks

QBO is QuickBooks Web Connect. Like QFX, it is OFX with vendor-specific identifiers, but those identifiers target QuickBooks. QuickBooks Online and Desktop import QBO files cleanly because the structure carries exactly what they expect, including unique transaction IDs that prevent duplicates. The guide on what a QBO file is goes deeper on this format.

Side by side

Why you cannot just rename the file

It is tempting to rename a .qbo to .ofx and hope it imports. It usually does not work, because the identifiers inside the file still point at the original software. The importer reads the contents, not just the extension, and rejects or mishandles a mismatched file. Proper conversion rewrites the internal structure and identifiers to match the target format, which is why a converter beats a rename.

How to convert between them

BankConvert reads any of these formats and writes whichever one your software needs, rewriting the identifiers so the import is clean. Common moves include:

• Convert OFX to QBO when you have an OFX but need it in QuickBooks.
• Convert QBO to QFX when you want QuickBooks data in Quicken.
• Convert QFX to QBO when a Quicken export needs to go into QuickBooks.

If you just want to read any of them, convert to a spreadsheet instead. For example you can convert an OFX file to CSV and open it in Excel as plain columns.

Which one should you use?

• Using QuickBooks? Use QBO.
• Using Quicken? Use QFX.
• Using Xero, GnuCash, or something else? OFX is usually the safest bet.
• Just want to read the data? Convert to CSV.

Security and scope

These files carry real account activity, so handle them like any sensitive document. BankConvert encrypts files, processes them only to convert, then discards them, and never stores or sells your data, as set out on the security page. And BankConvert converts files, it does not provide accounting or tax advice, so review the transactions after any conversion.

Bottom line

OFX, QFX, and QBO are the same family with different surnames. OFX is the open standard, QFX speaks Quicken, and QBO speaks QuickBooks. Match the format to your software, do not rely on renaming, and when the file you have does not match the tool you use, convert it properly so the import just works.
