CSV vs Excel vs QBO vs QIF: Which Export Do You Actually Need?
By Tarun Vashishth · Published
Every bank statement converter offers a row of format buttons and assumes you already know which one you want. Here's what each actually is, in plain terms, and how to pick.
| Format | What it is | Use it for |
|---|---|---|
| CSV | Plain comma-separated text — the universal fallback | Spreadsheets, most accounting software's generic import |
| Excel (.xlsx) | A real, typed spreadsheet — dates and numbers as actual cell types, not text | Analysis, pivot tables, budgeting formulas |
| QBO | An OFX document with Intuit-specific headers, saved with a .qbo extension | QuickBooks Web Connect import |
| OFX | The same underlying format as QBO without the Intuit headers | Other accounting software that speaks OFX directly |
| QFX | Quicken's variant of the same OFX format | Quicken import |
| QIF | An older, simpler line-based transaction format (date, amount, payee, per entry) | Legacy software and some import tools that predate OFX |
CSV: the one that always works, and loses the most
CSV is just text — a header row, then one line per transaction, fields separated by commas. Every spreadsheet and nearly every accounting tool can open it. What it doesn't carry: cell types. A date in a CSV is a string that looks like a date until whatever opens it decides to parse it as one — and if it doesn't, you get "01/15/2026" sitting in a column that a SUM() or date filter silently ignores. It also can't express a signed amount as anything other than a number written with a minus sign, which is fine for most uses but means there's no formatting, no bold header, nothing beyond raw data.
Excel: the one to pick when you're going to work with the data
An .xlsx file carries real types — a date cell is a date, a number cell is a number formatted to two decimals, not a string that happens to look numeric. That distinction is exactly what a pivot table or aSUMIF formula depends on. If you're about to build a budget, a chart, or any kind of analysis on top of the export, Excel saves you a cleanup pass CSV usually requires first.
QBO / OFX / QFX: the ones for accounting software, not humans
These three are really one format — OFX — wearing different extensions for different software's import dialogs. The reason to use one over CSV: each transaction carries a unique ID (FITID in OFX terms), which lets the receiving software recognize a transaction it's already imported and skip it instead of posting a duplicate. CSV has no equivalent — reimporting the same CSV twice usually means reviewing and deleting duplicates by hand. If you're importing directly into QuickBooks (QBO), Quicken (QFX), or other OFX-aware software (OFX), and especially if you expect to import statements more than once, this category is worth the extra step over CSV. See theQBO-specific guide for what the INTU.BID field is and why it's usually left blank.
QIF: the format for older software
QIF predates OFX and is simpler — no bank ID, no unique transaction ID, just a date, an amount, and a payee per entry. It's mostly relevant if the software you're importing into is old enough to not support OFX, or explicitly asks for QIF. If you have a choice, OFX/QFX/QBO's duplicate-detection ID makes them the better pick for anything you might reimport.
The short version
- Feeding accounting software you'll import into more than once → QBO/OFX/QFX, matching the software.
- Analyzing, charting, or budgeting yourself → Excel.
- Something quick, or a tool that only takes CSV → CSV.
- Old software that specifically asks for it → QIF.
Whichever you pick, the underlying transaction list here is reconciled once, before export — every format is generated from the same verified data, so switching formats later doesn't mean re-verifying anything.
