Transform OFX financial data from Quicken, MS Money, and bank downloads into Excel-ready CSV files. Extract transaction details, analyze in spreadsheets, and import into any accounting software.

Try for one week

Converting OFX to CSV requires specialized software to parse the Open Financial Exchange XML format and extract transaction data into spreadsheet-compatible columns. OFX files from Quicken, MS Money, and bank Web Connect downloads contain structured financial data that Excel cannot natively read.

With Zera Books, upload any OFX file and receive a clean CSV or Excel file in under 60 seconds. Our platform automatically parses all OFX transaction fields—dates, amounts, payees, memos, check numbers, and account information—preserving every detail while converting to a universal format compatible with Excel, Google Sheets, QuickBooks, Xero, and any accounting platform. For direct QuickBooks import, explore our QBO format converter.

Quick Takeaways:

OFX format: XML-based financial data exchange standard used by banks and Quicken
Excel compatibility: Requires conversion to CSV/XLSX—Excel can't open OFX natively
Data preservation: All transaction details, dates, amounts, and memos maintained
Unlimited conversions: Process multiple OFX files from different accounts simultaneously
Security: Bank-level encryption, files auto-deleted after conversion

Unlike free online converters that may store your financial data or limit conversions, Zera Books provides unlimited OFX to CSV conversion with enterprise-grade security. Our AI automatically categorizes transactions for accounting import, handles batch processing for multiple files, and ensures every transaction field is accurately extracted and formatted for immediate use in Excel or your accounting software.

What is OFX File Format?

OFX (Open Financial Exchange) is an industry-standard format for exchanging financial data between institutions and software applications. Developed collaboratively by Microsoft, Intuit, and CheckFree, OFX enables secure transmission of account information, transaction history, and balance data from banks to personal finance software.

Common OFX Sources

• Bank Web Connect downloads
• Quicken exports (all versions)
• MS Money transaction files
• Credit union statement downloads
• Investment account data
• GnuCash and Moneydance files

OFX Data Fields

• Transaction dates and times
• Debit and credit amounts
• Payee/merchant names
• Memo and description fields
• Check numbers and references
• Account balances and types

Why Excel Can't Open OFX Files Directly

OFX files use XML structure with financial-specific tags (like <STMTTRN>, <TRNAMT>, <DTPOSTED>) that Excel doesn't recognize. While technically a text file, OFX requires parsing logic to:

Extract transaction data from nested XML tags
Convert OFX date formats (YYYYMMDD) to readable dates
Organize data into columns (Date, Description, Amount, Balance)
Handle multiple accounts and transaction types

Zera Books automates this entire parsing process, delivering clean CSV files with properly formatted columns ready for Excel pivot tables, formulas, and analysis.
