Hi there, @GBCFO.

I am here to assist you on how to export or copy row in (QBO) QuickBooks Online.

If you are referring to copy transactions in Banking, you can export this to excel. Here’s how:

1.Go to Banking tab, click Banking
2.Beside the Gear icon, click Export to Excel.

Then, system will automatically download the file.

You can refer to this link to export report, list and other data from QuickBooks Online.

If you want to copy particular transaction like expense, estimate and invoice, you can also do this:

1.Go to Expense.
2.On the right side, click the Drop down arrow you can see options like copy, delete or void.
3.Then, tick Copy.

If you need to export non-posting transaction and attachments, here’s the link.

Please let me know if you have any problems along the way. I'm always willing to assist you. Have a wonderful day!
