AboutIIF to CSV

Convert QuickBooks IIF transaction files into CSV rows for spreadsheet review or migration to another accounting system.Category: Financial Formats

The IIF to CSV tool is compatible with:QuickBooks DesktopAccounting Migrations. This tool alone can help you manage and analyze your data effectively. However, a composed workflow using QIF TO CSV, OFX TO CSV may provide even more powerful data processing capabilities. Consider exploring these related tools for a comprehensive data solution.
IIF is QuickBooks Desktop's own tab-delimited interchange format for transactions, lists and other accounting data, and it's still the format most QuickBooks-to-anything migrations run into first. This tool reads the "!TRNS" header line to learn the column layout for that block, then maps every following "TRNS" data row onto those same column names — so you get a properly labeled CSV instead of a wall of tab-separated codes. It's built for the migration scenario: pulling transactions out of QuickBooks Desktop to move into another accounting system, or just to review a batch of exports in a spreadsheet before deciding what to do with them. Everything runs locally in your browser, which matters here specifically because IIF exports routinely contain full transaction-level financial detail you don't want passing through a third-party server.

Frequently Asked Questions:

What is IIF used for?

It's QuickBooks Desktop's own tab-delimited format for transactions and list data, commonly hit when migrating off QuickBooks.

Does the converter understand QuickBooks-specific transaction types?

It maps whatever columns your IIF export's header defines, so it adapts to your specific transaction structure.
