What Is the Excel to OFX Converter?
The FinancialDataTools.com Excel to OFX Converter is a free, browser-based tool that transforms Excel (XLSX) financial transaction data into valid Open Financial Exchange (OFX) 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 Excel sources into OFX-compatible software — banks, accounting platforms, Quicken, and similar applications — without writing any conversion code.
Try the Excel to OFX Converter — runs entirely in your browser and never uploads your files.
Open the Converter →Supported Input Format
The converter accepts Excel (XLSX) 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 | amount | description | memo | id 2026-01-15 | -125.50 | Grocery Store | Weekly shopping | TXN001 2026-01-16 | 2500.00 | Payroll | January salary | TXN002
Field Mapping
The converter automatically maps common field name variations to their OFX equivalents. You do not need to rename your fields before loading — the converter recognises aliases case-insensitively:
| Logical Field | Accepted Names | Description |
|---|---|---|
| date | date, dtposted, transaction_date, trans_date, posted_date, value_date | Transaction date — any date format Excel uses |
| amount | amount, trnamt, transaction_amount, debit_credit, value | Transaction amount — negative for debits |
| description | description, name, desc, payee, memo, narrative, reference, details | Payee name or description |
| memo | memo, notes, note, reference, details, narrative | Additional memo or narrative |
| id | id, fitid, transaction_id, trans_id, reference_id, txn_id, ref | Unique transaction ID |
Note: Fields not in the mapping table are included in the source preview table but are not written to the OFX output. Only transaction-relevant fields are used in the conversion.
The Toolbar
The toolbar across the top provides all primary actions:
| Control | Function |
|---|---|
| Open | Opens a system file picker to select your Excel file |
| File name display | Shows the name of the currently loaded file |
| Convert to OFX | Converts the loaded data and renders the OFX output |
| Export OFX | Downloads the converted OFX file; enabled only after conversion |
| Reset | Clears all state and returns the tool to its initial empty state |
You can also drag and drop a Excel 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 OFX 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 OFX, the panel renders the full OFX output as plain text so you can inspect it before downloading.
OFX Output Structure
The output is a valid OFXSGML file. Each transaction becomes an OFX <STMTTRN> block with type, date, amount, FITID, name, and memo fields.
The output is ready for import into financial software that accepts OFX files. No post-processing is required.
Output File Naming
The downloaded OFX file is named to match your input file. Only the extension is changed to .ofx. A file named transactions.excel produces transactions.ofx. This keeps your file set organised without requiring any manual renaming.
Exporting the OFX File
After conversion, click the Export OFX button in the toolbar. The browser downloads the file directly to your downloads folder. The Export OFX 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 OFX 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 Excel to OFX 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.
