Convert OFX to JSON Online

Paste an OFX table below, edit it if you need to, and get JSON back. The conversion runs in your browser, so nothing is uploaded, there is no size limit and there is no signup.

From

The only part of this site that uses a server. The address is sent to it so the page can be fetched, because a browser is not allowed to fetch someone else's page itself. Your own files are never involved.

Nothing here is uploaded. The parsing happens on this page.

The output will appear here once there is a table to convert.

What OFX is

OFX is the format behind the Download Transactions button on your bank's website. Version 1 is SGML, where a leaf element has an opening tag and no closing one. Version 2 is real XML. QFX is Intuit's variant of the same thing with a few extra tags, which is why a .qfx file opens in Quicken and is refused by software that only knows plain OFX.

Retail banks, credit card issuers and brokerages, because it is what Quicken and Microsoft Money asked for and the industry standardised on.

What JSON is

JSON is a text format for nested data: objects with named keys, arrays, strings, numbers, booleans and null. It has no date type and no comments.

Every web API, most configuration files and anything that talks to JavaScript.

What changes when you convert OFX to JSON

Each STMTTRN block becomes a row: date, amount, type, payee, memo, cheque number and the bank's own transaction id. The account number and currency come from the statement header and are added to every row, so a file merged with another still says which account it came from. Both the SGML and the XML flavour are read the same way.

You choose the shape. An array of objects is the default and the one most code expects. A 2D array is smaller. Column arrays suit charting libraries. A keyed object suits lookups by id.

What carries over from OFX to JSON

JSON can express everything OFX holds about a table, so this conversion is about shape rather than loss.

Both formats record types, so numbers, booleans and nulls survive as themselves rather than as text.

A worked example

Three rows of staff data, with an identifier that has a leading zero, a value containing a comma, a value containing quotes and one blank cell. Those are the four places formats disagree, so they are the four places to look.

Questions

How do I convert OFX to JSON?

Paste your OFX into the box above or drop the file onto it. Check the table in the grid, then copy or download the JSON from the output panel. It takes one step and the data never leaves your browser.

What is the difference between OFX and QFX?

QFX is OFX with Intuit-specific tags added, most importantly a bank identifier that Quicken uses to decide whether it will accept the file. The transaction data is identical, which is why anything that reads OFX reads QFX. Banks often charge for the QFX version of the same download.

Why did my zip code lose its leading zero?

Type inference turned the text 07030 into the number 7030. Tablizer leaves inference off by default for exactly this reason, and refuses to convert any value starting with a zero followed by a digit even when it is on.

Is there a limit on file size?

No. The work happens on your own machine, so the limit is your machine's memory rather than an upload cap. A file with tens of thousands of rows converts in a second or two.

Is my data uploaded anywhere?

No. The parsing and generating are done by JavaScript running on this page. You can watch the network tab while you convert and see that nothing is sent.
