Extract text from IIF files
To convert your IIF file to another format, you need Intuit QuickBooks or other Data software.
To convert other file formats to the "Accounting Data Import" file type, you need software like Intuit QuickBooks or a similar tool.
The .IIF (Intuit Interchange Format) is a legacy text-based file type designed by Intuit for importing and exporting lists and transactions in QuickBooks Desktop. While it acts as a bridge between disparate financial systems, the format is notorious among accountants for its rigid structure and lack of error checking. Unlike modern APIs or QBO bank feed files, .IIF files bypass the standard QuickBooks business logic layer during import. This means a malformed file can force corrupt data into your company file without warning, potentially requiring a full database rollback.
Because .IIF files are technically tab-delimited text, they can be opened in basic editors like Microsoft Notepad, but the raw data - filled with proprietary headers like !TRNS and !SPL - is difficult to interpret or audit manually. Users often struggle when third-party payroll or inventory software generates an .IIF that QuickBooks rejects due to minor syntax errors. To safely view, clean, or migrate this data, the best workflow is converting the .IIF to CSV or Microsoft Excel (XLSX). This allows for easy column filtering and data validation before attempting an import. For archiving financial records or sharing transaction logs with clients who lack accounting software, converting to PDF is the standard for preserving the layout without risking accidental edits.
Convert.Guru analyzes your IIF file, detects the exact format, and lets you read the text inside.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our IIF converter.
