Why convert IIF to ICO?
An IIF file is an Intuit Interchange Format export, a tab-separated text file used to move lists and transactions into and out of QuickBooks Desktop. The ICO shows an “IIF document” heading followed by every row of the file exactly as written, set in a monospaced font, header rows included.
ICO output is a 256 × 256 pixel Windows icon: the image is scaled to fit with its proportions kept, and the surrounding space is transparent.
