Do I have to do the conversion of my data from QuickBooks online to desktop myself?

Hello, Donald Johnston. 

Yes, that's correct. I'm willing to point the details to guide you with the conversion process. 

We have a guide to help you with the process of converting your Online data to the Desktop version. It comes with a migration tool to assist you as well. 

To get started with the conversion, you'll want to follow the steps outlined from this article: Export and convert your QuickBooks Online data to QuickBooks Desktop. 

It should be noted that both programs have different functionalities and features, so there will be limitations about the conversion process. 

This article highlights those limitations: Limitations when you convert from QuickBooks Online to QuickBooks Desktop.

Aside from the do-it-yourself guide, our support can also lend a helping hand in converting your data. Contact them if ever you need someone to assist you. 

After converting and setting up your data in the Desktop version, you can start working on your company file. If you're unfamiliar with the processes, we have other guides to help you get started on QuickBooks Desktop. 

Check them out in the general help page for QuickBooks Desktop. Just browse a topic and select an article.
