How can I upload my data without having QB desktop?
Hi there Denial!
We appreciate you for taking the time to visit the Community.
To import your data to Online, you need to have QuickBooks Desktop. Since you only have a backup file (.qbb file), you can download an updated trial from the QuickBooks Desktop Trial Links.
To import the data, please follow the steps in this article: Import into QuickBooks Online from QuickBooks Enterprise.
If you have other questions, please don’t hesitate to reach out again.
