Convert CSV to OFX Format
Learn how to convert CSV files to OFX format for seamless import into QuickBooks, Xero, Sage, and other accounting software. Complete guide with automated conversion tools and best practices.
To convert CSV to OFX format, you need a conversion tool that maps CSV columns (date, description, amount) to the standardized OFX structure required by accounting software. OFX (Open Financial Exchange) is the industry standard format used by QuickBooks, Xero, Sage, and most financial applications for importing bank transactions.
While banks typically provide statements in PDF or CSV format, accounting software requires OFX format to properly structure transaction data with account information, dates, payees, and amounts. Manual conversion is time-consuming and error-prone, especially when dealing with multiple accounts or large transaction volumes.

What is OFX Format?
OFX (Open Financial Exchange) is an open standard file format designed for exchanging financial data between financial institutions, accounting software, and personal finance applications. Developed jointly by Microsoft, Intuit, and CheckFree in 1997, OFX has become the industry standard for financial data interchange.
Why OFX Matters for Accounting
Unlike simple CSV files that contain only basic transaction data, OFX files include structured information about:
- Account identification: Bank account numbers, routing numbers, and account types
- Transaction details: Dates, amounts, payees, check numbers, and transaction types
- Balance information: Opening and closing balances for reconciliation
- Metadata: Transaction IDs for duplicate detection and reference numbers
- Currency data: Multi-currency support for international transactions
This structured format ensures that when you import transactions into QuickBooks, Xero, or other accounting software, all relevant information is preserved and properly categorized. The software can automatically match transactions, detect duplicates, and maintain accurate records for reconciliation and reporting.
OFX vs. Other Financial File Formats
| Format | Use Case | Compatibility |
|---|---|---|
| OFX | Universal standard for most accounting software | QuickBooks, Xero, Sage, GnuCash, most platforms |
| QFX | Quicken-specific variant of OFX | Quicken only |
| QBO | QuickBooks Desktop import | QuickBooks Desktop only |
| IIF | QuickBooks Desktop alternative format | QuickBooks Desktop only |
| CSV | Simple data export, requires manual mapping | Universal but limited functionality |
OFX strikes the perfect balance between universal compatibility and rich data structure, making it the preferred format for professional bookkeepers and accountants who need reliable, automated imports across multiple software platforms.
