About IIF files
The .IIF file is an Intuit Interchange Format file, primarily used by QuickBooks to import and export lists and financial transactions. A much rarer variant is the Symbian OS multi-bitmap icon file. Users typically open financial .IIF files using QuickBooks Desktop or a spreadsheet application like Microsoft Excel. You can read more about QuickBooks on Wikipedia. The main disadvantage of the .IIF format is its extreme fragility. It is a proprietary, tab-delimited text format with very strict header requirements. If a user edits the file in a standard text editor and accidentally adds a space instead of a tab, the file becomes corrupted and will fail to import. Furthermore, older versions of QuickBooks offer poor error handling, meaning a broken .IIF file can silently damage your financial ledger. Because of these risks, you often need to convert this file into a safer, more readable format before analysis. For data editing and auditing, convert the file to CSV or XLSX. For the legacy Symbian image format, convert to PNG or JPG for web viewing. Drop your file here to view and convert it securely right in your browser.

The IIF Converter Story
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.
