IIF to CSV Converter

Convert QuickBooks IIF files into CSV format so you can review, clean and analyze transaction data in spreadsheets.

Create your CSV file

Your IIF file is processed locally in this browser and is not uploaded to our servers.

Choose an .iif file containing QuickBooks transaction groups. UTF-8, Windows-1252 and UTF-16 text files up to 10 MB are supported.

Transaction and split fields are placed into consistent CSV columns, with physical source lines and balance differences retained for review.

IIF parsing and CSV generation happen on your device. No accounting file or transaction data is sent to an API.
