Hi there, cubascookin.adm.
QuickBooks Online International version doesn't have an option to import transactions. Here are the data that can be imported into QuickBooks Online.
On the other hand, if you’d like to use a third party app to handle the importing transaction, we don't have any specific programs that we can recommend here. However, I wanted to point you to our App Center. This is where you can find all the third party applications that are sure to work with QuickBooks Online. There are a lot of different options in there, so you may find one that works for you.
Check out this page that has all our supported apps: QuickBooks Apps.
You may also send your feedback and product suggestion by going to the gear icon then select feedback. We have a product release every month and most of the enhancements come from the customer's feedback.
Feel free to visit us again if there's anything else you'd like to share, or if you need help with QuickBooks Online. Have a great day!
