Unfortunately, no. Intuit’s policy is stated in this Intuit knowledgebase article.
Intuit Interchange Files are delimited text files that can be used to import and export data when working with a QuickBooks company file (.qbw).
While the ability to use IIF files is still included in QuickBooks, most newer programs have adopted techniques that make use of the Intuit Software Development Kit (SDK). That has caused the use of IIF files to decline over time, something that Intuit has encouraged by its policy of non-support.
