Convert IIF Files to Excel
Extract QuickBooks Data Into Clean, Editable Spreadsheets
Transform QuickBooks IIF export files into structured Excel spreadsheets. Extract transactions, accounts, vendors, customers, and all data types from QuickBooks Desktop IIF files — ready for analysis, sharing, or migration.
What Is an IIF File?
IIF — Intuit Interchange Format
IIF (Intuit Interchange Format) is QuickBooks Desktop's proprietary tab-delimited text format for exporting financial data. When you use File > Utilities > Export in QuickBooks Desktop, the result is an IIF file containing all your transaction history, chart of accounts, vendor list, customer list, and more.
IIF files use a structured header-record format where each data type starts with a header line (like !TRNS for transactions or !ACCNT for accounts) followed by data rows. This structure is powerful but difficult to read or edit without the right tools.
What Software Uses IIF Files?
IIF files are generated exclusively by QuickBooks Desktop (Pro, Premier, and Enterprise). They were designed for:
- •QuickBooks Desktop: Transferring data between installations or company files
- •Data Migration: Moving from QuickBooks to other accounting software
- •Audit Trails: Exporting historical transaction data for compliance
- •Reporting: Sending data to accountants who need raw records
Why Convert IIF to Excel?
Analyze QuickBooks Data
Use Excel's powerful analysis tools — pivot tables, VLOOKUP, charts, and conditional formatting — to gain insights from your QuickBooks transaction history that are impossible in the raw IIF format.
Share with Non-QuickBooks Users
Share financial records with accountants, auditors, investors, or partners who do not have QuickBooks. Excel is universally understood and requires no special software license to open.
Migrate to Other Systems
Excel is the universal bridge format for migrating data to Xero, Sage, FreshBooks, or any other accounting platform. Export IIF to Excel first, then reshape the data for your target system.
IIF File Data Types — What Gets Extracted
Financial Records
- !TRNS — Transactions: All journal entries, checks, deposits, invoices, and bills with dates, amounts, and memo fields
- !SPL — Split Lines: Individual line items within multi-category transactions, preserving account assignments
- !ACCNT — Chart of Accounts: Your complete account list with types, balances, and descriptions
- !CLASS — Classes: Class tracking data for departmental or project-based accounting
Entity Records

- !CUST — Customers: Customer records with contact information, credit limits, and payment history
- !EMP — Employees: Employee data including payroll information and direct deposit details

IIF vs QBO vs CSV — Which Format Do You Have?
| Format | Source | Contains | Use Case |
|---|---|---|---|
| IIF | QuickBooks Desktop export | Transactions, accounts, vendors, customers, employees, items | Data migration, archival, sharing QuickBooks data with non-QB users |
| QBO | Bank download or PDF conversion | Bank transactions only (date, amount, description) | Importing bank transactions into QuickBooks Online |
| CSV | Any system, bank, or converter | Tabular data in plain text format | Universal import/export for any accounting software |
| OFX | Bank download or PDF conversion | Bank transactions in structured XML-like format | Importing into Quicken, GnuCash, Microsoft Money |
Have a PDF bank statement instead of an IIF file? Convert your bank statement to CSV or convert to QBO for QuickBooks Online.
Which Banks Work with QuickBooks IIF?
Major US banks support direct QuickBooks Desktop integration via WebConnect, which uses the same underlying data as IIF. If your bank's WebConnect download stopped working, converting a PDF bank statement to IIF-compatible format is the alternative.

Frequently Asked Questions About IIF to Excel
What is an IIF file?
IIF (Intuit Interchange Format) is QuickBooks' proprietary tab-delimited text format for importing and exporting financial data. IIF files contain structured records for transactions, accounts, vendors, customers, employees, and items. They are generated when you export data from QuickBooks Desktop and are used to transfer data between QuickBooks installations or migrate to other systems.
How do I convert IIF to Excel?
Upload your IIF file to our converter. Our parser reads the QuickBooks IIF format and extracts all data types — transactions, accounts, vendors, customers — then exports them to a clean Excel spreadsheet with properly labelled columns for date, account, amount, description, and memo. The conversion takes under 30 seconds.
Why convert IIF files to Excel?
Excel gives you far more flexibility than the raw IIF format. You can apply filters, create pivot tables, build charts, run custom formulas, and share data with accountants or stakeholders who do not have QuickBooks. Excel is also easier to audit and manipulate when migrating data to other accounting systems like Xero or Sage.
What data types are included in an IIF file?
IIF files can contain multiple record types: !ACCNT (chart of accounts), !TRNS (transactions), !SPL (transaction split lines), !VEND (vendors), !CUST (customers), !EMP (employees), !INVITEM (inventory items), and !CLASS (classes). Our converter extracts all these record types into separate Excel tabs for easy navigation.
Is the IIF to Excel conversion accurate?
Yes. Our parser correctly handles all IIF data types including multi-line transactions with split lines, date formats (MM/DD/YYYY), currency amounts, and special characters. We preserve the relationship between transaction headers (TRNS) and their split lines (SPL) so totals always match.
Can I open an IIF file directly in Excel?
Technically yes — IIF files are tab-delimited text files so Excel can open them. However, the raw output is hard to read because IIF uses header records like !TRNS and ENDTRNS that break the columnar structure. Our converter restructures this into clean, usable rows with proper column headers.
Which QuickBooks versions generate IIF files?
QuickBooks Desktop (Pro, Premier, Enterprise) generates IIF files via File > Utilities > Export. QuickBooks Online does not natively export IIF — it exports CSV or QBO instead. IIF was QuickBooks Desktop's primary data transfer format before QBO became the bank import standard.
What is the difference between IIF and QBO formats?
IIF (Intuit Interchange Format) is a general-purpose export format for QuickBooks Desktop covering transactions, accounts, vendors, and more. QBO (QuickBooks Online Bank File) is specifically for importing bank transactions into QuickBooks Online — it is a variant of the OFX standard. If you have a bank statement, convert to QBO. If you have a QuickBooks export, convert IIF to Excel.
