Hi there, @vandersonremax.
Thanks for sharing your concern in the Community space. I can provide information about importing Journal Entries from an Excel spreadsheet.
We would want to give the best enhancement of our products that are right for our customers' business need. That is why, our Development Team are continuing on determining what features and systems to implement for users.
At this time, the ability to import Journal Entries isn't available in QuickBooks Online. You may want to check out a third-party app which can integrate with the software.
For more information about importing data, look into this article: https://community.intuit.com/articles/1458771.
That information should help you load Journal Entries using an Excel spreadsheet. Feel free to visit us again in the Community if you have other questions about QuickBooks. I'm always here to help. Have a nice day!
