The file extension IIF is associated with Intuit QuickBooks, which is an application used for working with financial data. Intuit QuickBooks is typically used for small business accounting and can also be used for personal finance purposes.
IIF file extensions are a data file type that contains financial information and instructions which pertain to exporting financial data to another application. IIF files are typically in a plain text format and have a similarity to a TSV file, which is a tab delimited file where each field within a financial record is indicated with a tab. This allows to the file to be easily imported into a database and exported to other applications.
IIF file extensions are a proprietary file format and are also known as an Intuit Interchange File. They are in tab-based text format since QuickBooks uses this proprietary format to facilitate importing and exporting of files. This allows the files to be used with a number of different applications.
