Thanks for reaching out to us about importing journal entries in QuickBooks Online, Aaron_E123. 

I can see how additional options for importing transactions, such as journal entries, would be beneficial to you. I recommend sending this request straight to our product engineers through feedback consideration for software updates. QuickBooks Online is constantly evolving and adding features based largely on the suggestions of users, like yourself. 

 Alternatively, you can send feedback to them by clicking the Gear icon, then selecting Feedback.
