What Is the JSON to QFX Converter?

The FinancialDataTools.com JSON to QFX Converter is a free, browser-based tool that transforms JSON financial transaction data into valid Quicken Financial Exchange (QFX) format. It processes your file entirely inside your browser tab — no file is ever transmitted to any server.

The converter is built for financial analysts, accountants, and developers who need to move transaction data from JSON sources into QFX-compatible software — banks, accounting platforms, Quicken, and similar applications — without writing any conversion code.

Try the JSON to QFX Converter — runs entirely in your browser and never uploads your files.

Supported Input Format

The converter accepts JSON files containing financial transaction data. The expected structure is an array or list of transaction records, each with fields for date, amount, description, and an optional identifier.

Example input:

[
  {
    "date": "2026-01-15",
    "amount": -125.50,
    "description": "Grocery Store",
    "memo": "Weekly shopping",
    "id": "TXN001"
  },
  {
    "date": "2026-01-16",
    "amount": 2500.00,
    "description": "Payroll",
    "memo": "January salary",
    "id": "TXN002"
  }
]

Field Mapping

The converter automatically maps common field name variations to their QFX equivalents. You do not need to rename your fields before loading — the converter recognises aliases case-insensitively:

Logical FieldAccepted NamesDescription
datedate, dtposted, transaction_date, trans_date, posted_date, value_dateTransaction posting date (YYYY-MM-DD recommended)
amountamount, trnamt, transaction_amount, debit_credit, valueTransaction amount — negative for debits, positive for credits
descriptiondescription, name, desc, payee, memo, narrative, reference, detailsPayee name or transaction description
memomemo, notes, note, reference, details, narrativeExtended memo or reference text
idid, fitid, transaction_id, trans_id, reference_id, txn_id, refUnique transaction identifier

Note: Fields not in the mapping table are included in the source preview table but are not written to the QFX output. Only transaction-relevant fields are used in the conversion.

The Toolbar

The toolbar across the top provides all primary actions:

ControlFunction
OpenOpens a system file picker to select your JSON file
File name displayShows the name of the currently loaded file
Convert to QFXConverts the loaded data and renders the QFX output
Export QFXDownloads the converted QFX file; enabled only after conversion
ResetClears all state and returns the tool to its initial empty state

You can also drag and drop a JSON file onto the left (source) panel to load it.

Source Panel

The left panel is the source panel. Once you load a file, it renders a scrollable table preview showing your transaction records — field names in the header row, data rows below.

For very large files, the preview is capped at 500 rows. A notice confirms how many rows are previewed versus the total. The full dataset is still converted — the preview cap only affects the on-screen table, not the QFX output.

Numeric cells are highlighted in blue and right-aligned. Empty or null cells display as NULL.

Output Panel

The right panel is the output panel. Before conversion it shows a placeholder. After you click Convert to QFX, the panel renders the full QFX output as plain text so you can inspect it before downloading.

QFX Output Structure

The output is a valid QFX file (OFX format with Quicken extensions including <INTU.BID>3000</INTU.BID>). Each transaction becomes a <STMTTRN> block.

The output is ready for import into financial software that accepts QFX files. No post-processing is required.

Output File Naming

The downloaded QFX file is named to match your input file. Only the extension is changed to .qfx. A file named transactions.json produces transactions.qfx. This keeps your file set organised without requiring any manual renaming.

Exporting the QFX File

After conversion, click the Export QFX button in the toolbar. The browser downloads the file directly to your downloads folder. The Export QFX button is disabled until a successful conversion has been completed.

Resetting for Another Conversion

The Reset button clears all state — the loaded file, the source preview, the QFX output, and all status badges — and returns the tool to its initial empty state. You can also click Open again to load a new file without resetting.

Privacy & Security

The JSON to QFX Converter is built privacy-first. Your file is parsed and converted entirely inside your browser tab using JavaScript — no file content is ever transmitted to any server.

This makes the converter appropriate for sensitive financial data including bank transaction exports, payroll records, brokerage transaction history, and proprietary financial model outputs.

Closing the browser tab clears all data from memory immediately. No data is written to any persistent browser storage.
