What Is the QFX to JSON Converter?
The FinancialDataTools.com QFX to JSON Converter is a free, browser-based tool that transforms Quicken Financial Exchange (QFX) files into JSON (JSON) format. All processing runs entirely inside your browser tab — no file is ever transmitted to any server.
The converter is built for financial analysts, developers, and accountants who need to move data between common financial file formats without writing any code or installing any software.
Try the QFX to JSON Converter — runs entirely in your browser and never uploads your files.
Open the Converter →About the QFX Input Format
Quicken Financial Exchange (QFX) is a widely used financial data format. QFX files typically contain structured records including transaction amounts, dates, account identifiers, and reference information. The QFX format is commonly produced by banking platforms, accounting software, and financial data export tools.
The converter accepts QFX files (.qfx) directly — no pre-processing or format conversion is required before loading.
About the JSON Output Format
JSON (JSON) is a widely supported data interchange format. Converting your QFX data to JSON allows you to import it into applications, databases, and services that accept JSON as an input format.
The converter produces a properly structured JSON file (.json) that preserves all fields and values from your original QFX source data.
The Toolbar
The toolbar across the top provides all primary actions for the conversion workflow. Use Open to browse for your QFX file, or drag and drop the file onto the source panel. Once a file is loaded, click Convert to JSON to generate the output. Click Export JSON to download the result. The Reset button clears all state for a new conversion.
Source (QFX) Panel
The left panel shows your loaded QFX data as a table preview. Column headers are shown in the first row. For large files, the preview is capped at 500 rows — a notice is shown if your file exceeds this limit. The full dataset is always converted regardless of the preview cap.
Output (JSON) Panel
The right panel displays the converted JSON output. Before conversion it shows a placeholder. After clicking Convert to JSON, the panel renders the full output content. The panel is scrollable for any file size.
Output File Naming
The downloaded JSON file is named to match your input file — only the extension is changed to .json. A file named export.qfx produces export.json. This keeps your file set organised without requiring any renaming.
Privacy & Security
The QFX to JSON 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 statements, transaction exports, and accounting records.
Closing the browser tab clears all data from memory. No data is written to localStorage or any persistent browser storage.
Use Cases for Financial Data
Converting QFX to JSON is a routine step in many financial data workflows. Common scenarios include importing data into accounting software that requires JSON format, migrating historical records between financial platforms, sharing structured financial data with counterparties, and preparing data for analysis or reporting pipelines that consume JSON files.
