Hello, Rozmore13. Let me share additional information about the supported file types in QuickBooks Online.
The following are the currently supported file formats when adding attachments.
- PDF
- JPEG
- PNG
- DOC
- XLSX
- CSV
- TIFF
- GIF
- XML
If you're referring to importing bank activities, the following are the ones that are supported:
- CSV file: A common file format used for text files that contain tabular data. In CSV files, each field of text is separated by a comma, semi-colon, or other special characters.
- XLS/XLSX file: XLS is the file format of Microsoft Excel 1997-2003. Microsoft Excel 2007 and newer use the XLSX file format.
- Google Sheets: A cloud-based spreadsheet created in Google Drive.
In your example, Asc and IFF are likely not on the list of acceptable file types.
Here are resources you can read for additional reference:
