QBO File Checker
About to import a QBO file into QuickBooks? Check it first. We validate the file's structure, closing balance, statement period, and the duplicate risks QuickBooks won't warn you about until reconciliation breaks.
Drop a .qbo, .ofx or .qfx file here, or click to browse
No account needed · The file is checked in memory and never stored
What this checker looks for
- Valid OFX structure — a .qbo file is OFX underneath; if the message set is missing, QuickBooks rejects the import outright.
- Ledger (closing) balance — reconciliation aims at this number. If it's missing or dated differently from the statement period, expect a fight at month-end.
- Duplicate FITIDs — QuickBooks treats a repeated transaction ID as already-imported and can silently skip real transactions.
- Look-alike transactions — same date, amount, and name appearing twice: sometimes genuine, often a double export.
- Dates outside the period — transactions dated outside the file's declared statement period are a common cause of beginning-balance mismatches.
Files converted with Convert Statement are built to pass every one of these checks — the running balances are verified against the statement itself before the QBO is generated. See how the QuickBooks converter works.
