Excel to IIF Converter

Convert Excel transaction sheets into QuickBooks IIF files with clean accounting-ready data.

Create your IIF file

Your Excel workbook is processed locally in this browser and is not uploaded to our servers.

Choose an .xlsx workbook containing dates, descriptions, and transaction amounts. Files up to 10 MB are supported.

The converter reads workbook worksheets, native Excel dates and numeric amounts. Each transaction receives an equal-and-opposite QuickBooks split.

Excel parsing and IIF generation happen on your device. The workbook is not uploaded and no conversion API is called.
