Hello there, dalajajaka.
QuickBooks Online currently doesn't allow exporting an IIF file type. However, you have the option to either search online for an IIF to CSV converter, or open the IIF file on a blank Excel workbook and save it as CSV file.
Here's how:
- Open your Microsoft Excel, and go to the File menu.
- Click New, and select Blank workbook.
- Click the File menu, and select Open.
- Go to the folder location, and look for the file name. You can set the file type to All Files so you can easily find the IIF file.
- Click Open.
- Go to the File menu, and click Save As.
- Choose a location to save the file, and enter the file name. Make sure the Save as type is Excel Workbook.
- Click Save.
Once done, you can continue importing your CVS file into QuickBooks Online.
If there's anything else you need, just let me know and I'm here for you.
