What Our Users Say
works good, wish it had batch mode
I was spending 4-5 hours every month reformatting exports manually. This tool paid for itself in the first use. The preview feature helped me verify the mapping before paying.
exactly what i needed thx!!
Super straightforward. Upload, convert, download. No account needed which is nice. Would give 5 stars if they add Xero support.
saved me hours of work
My accountant was so happy when I sent her the converted file. No more back-and-forth about date formats or missing columns. Everything imported correctly on first try.
fast and easy 10/10 would recommend
Been using this for 6 months for monthly reconciliations. Handles all the edge cases - partial refunds, multi-line orders, currency conversions. Very reliable tool.
Good tool, does what it says. Interface could be bit better but conversion quality is excellent. Using it for my 3 Shopify stores.
Switched from A2X to this. Way simpler for my needs - I don't need real-time sync, just clean data once a month. This delivers exactly that.
finally!! something that works with QB desktop!!

Why Validate IIF Files?
IIF Format is Strict
IIF files use a specific tab-delimited structure with TRNS/SPL/ENDTRNS rows.
All amounts in a transaction must sum to zero. Wrong structure causes import failures.
Validating first catches balance issues and structural problems.
What This Tool Checks
We validate your IIF file against QuickBooks Desktop requirements:
- Correct row structure (TRNS, SPL, ENDTRNS)
- Transaction amounts sum to zero
- Required columns present (TRNSTYPE, DATE, ACCNT, AMOUNT)
- Date format correct (MM/DD/YYYY)
- Valid transaction types
You get a detailed error report to fix issues before import.
Common Target Import Errors
Issues you might encounter when importing Source data to Target - and how we solve them
Invalid IIF Structure
IIF requires TRNS/SPL/ENDTRNS row structure
Missing ENDTRNS or mismatched rows
TRNS row, SPL rows, ENDTRNS row
Each transaction needs proper start/split/end structure
Ensure every TRNS has matching ENDTRNS
Unbalanced Transaction
Transaction amounts don't sum to zero
TRNS: 100, SPL: -90 (sum: 10)
TRNS: 100, SPL: -100 (sum: 0)
All amounts in a transaction must sum to zero
Adjust split amounts to balance the transaction
Invalid Transaction Type
TRNSTYPE is not a recognized QuickBooks type
SALE or RECEIPT
CASH SALE, INVOICE, CHECK, DEPOSIT
Use valid IIF transaction types
Change to valid type; note 'CASH SALE' has a space
Missing IIF Header
IIF file missing header rows (!TRNS, !SPL, !ENDTRNS)
File starts with data rows
!TRNS header row before data
IIF files need header rows starting with !
Add proper IIF headers at the start of file
Delimiter Issue
IIF must be tab-delimited, not comma-delimited
TRNS,CASH SALE,01/15/2025
TRNS[TAB]CASH SALE[TAB]01/15/2025
IIF format requires tab characters between fields
Re-export as tab-delimited or replace commas with tabs

Frequently Asked Questions
IIF (Intuit Interchange Format) is a tab-delimited text format for importing data into QuickBooks Desktop. It supports transactions, lists, and other data types.
Each transaction starts with a TRNS row, followed by SPL (split) rows, and ends with ENDTRNS. All amounts must sum to zero.
Common types include CASH SALE, INVOICE, CHECK, DEPOSIT, BILL, CREDIT MEMO, GENERAL JOURNAL. Use 'CASH SALE' (with space) for sales receipts.
IIF uses double-entry accounting. The TRNS row amount plus all SPL row amounts must equal zero for each transaction.
IIF import is supported in QuickBooks Pro, Premier, and Enterprise editions (2020-2025).
