Hello there, JACrescenzi.
Thanks for taking the time to reach us out here in the Community. I'd be happy to share some information on exporting custom spelled words.
The saved custom spelled words from your old version of QuickBooks should remain when you upgrade the software. However, you'll have to manually add them if you open the updated file to a different location.
Let's make sure the company file is saved on the same location. The default location for a QuickBooks Desktop company files is: C:\Users\Public\Public Documents\Intuit\QuickBooks\Company Files, from here you should be able to choose the version/year of your file.
Here's an article should you need reference on the process of upgrading to a new QuickBooks Desktop version.
To learn more about using the QuickBooks Spell Checker, you can refer to this article: Use QuickBooks Spell Checker.
Keep in touch if there's anything I can help you with aside from this. I'm always around to provide further assistance.
