Turn a .qbo Web Connect file into a validated .iif with the exact !TRNS / !SPL / !ENDTRNS header structure QuickBooks Desktop expects — no manual retyping.
Upload your .qbo file.
(Optional) Map QBO categories to your QuickBooks Desktop chart of accounts.
Download the .iif and import via File → Utilities → Import → IIF Files.
IIF gives QuickBooks Desktop batch-import power that QBO doesn't — splits, journal entries, chart-of-accounts mappings. Our converter parses the QBO, maps categories to your CoA (optional), and emits a strict IIF that QuickBooks Desktop imports without header validation errors.
Upload a small QBO sample and walk through column mapping, validation and preview before downloading — everything runs locally in your browser.
All parsing runs in your browser. Nothing is uploaded.
Every QBO conversion can also be exported directly to CSV, Excel (.xlsx), QuickBooks (.qbo) or OFX from the upload screen.
No — IIF is QuickBooks Desktop only.
Yes — GST/VAT lines can be auto-split into multi-line !SPL records.
Re-run the export; category mapping uses the latest snapshot.
