I'm doing fine today, santisusbielles. I'll help you get your file sorted out.

Exporting transactions from one QuickBooks file to another for a particular date is not available. But I would recommend the second suggestion you mentioned which is to copy the file and delete the transactions manually. This way, you can keep those that you need in your company file.

To learn more about managing your file in the Mac version, you can refer to the user's guide official eBook. From the PDF file, press CTRL + F on your keyboard and type import so you'll be routed to the import section where you can get the steps.

Don't hesitate to leave reply if you have more questions. Thanks.
