Thanks for coming back, @Arthur Götz.

We access the report you need to export to Excel and Select Edit from the Action column for the report you want to export. Then, press Export As PDF or Export As Excel. Also, the Transaction List with Splits report is available in the Essential version of QuickBooks Online (QBO). You'll want to upgrade your subscription to a free trial to run the reports you need in QBO.

On the other hand, the Memo/Description showing depends on the report you generate in QBO. If you run a report specific for transactions such as the Transaction List, it'll show the Memo you entered on the Memo field. However, if you're pulling up a report that shows details about the items for a particular transaction, it'll show the description per line item.

I'm looking forward to hearing from you again. If you have any other QuickBooks questions, please feel free to add a comment below. I'm always here to help. Take care always.
