Re: How do you import an iif file in Quickbooks Online

Hello there, @Doug2661.


Allow me to join this thread and share some more insights about importing files in QuickBooks Online (QBO).


@Rustler is correct. You're unable to import IIF files in QBO. If you wish to import your files, you can use either CSV (Comma Separated Values) or XLS/XLSX.


For additional reference and detailed instruction, please check the links below:

That should provide you enough information, @Doug2661. If you have follow-up questions, just reach out back to me. I'm still here to help you further.
