CSV vs QBO vs OFX vs QIF: Which Bank Transaction File Should You Use?
October 27, 2026 · Mirza Arham
The right file depends on what you want to do next. CSV is a table for review and mapping. QBO and OFX are structured bank-feed formats. QIF is an older interchange format still found in some exports. A different extension does not make incorrect transactions accurate, so inspect dates and amounts before switching formats.
Quick comparison
| Format | Typical use | Main caution |
|---|---|---|
| CSV | Spreadsheets and manual transaction imports | Columns and signs must be mapped correctly |
| QBO | QuickBooks Web Connect workflows | Institution and account compatibility varies |
| OFX | Finance software that accepts OFX | Importer support and account details vary |
| QIF | Legacy personal finance exports | Date formats and categories need review |
Choose CSV when you need visibility
A CSV is easy to open, filter, and correct in Excel or a text editor. It is the most transparent choice when extracting rows from a PDF. QuickBooks Online can also accept correctly formatted CSV files through its manual upload flow. Check whether it expects Date, Description, Amount or separate Debit and Credit columns.

Choose QBO or OFX only for a supported importer
A QBO or OFX file wraps each transaction in structured fields such as date, amount, and identifier. The generated file needs valid bank and account information and may still be rejected by a particular accounting program. When your bank supplies a native Web Connect file, try that first.
QuickBooks Desktop has its own Web Connect requirements. Intuit notes that importing .qbo files can require signing in to an Intuit account within Desktop. That is separate from any account on this converter site.

What if your bank provides QIF?
QIF can carry dates, descriptions, amounts, check numbers, and categories. Our QIF-to-QBO tool reads those fields and creates a QBO file after you provide bank and account details. Review ambiguous dates and transaction counts in the preview before importing.
