Hello there, @razzi.
I knew a few steps to export data from an expired trial to the new company file in QuickBooks Online (QBO). I'm here to help guide you how.
If you can still access the expired trial account in QBO, then, you can simply export the data to Excel. Once completed, you can then import the data to your new account/file.
To export the data/file to Excel:
Once completed, you can now import the data to your new QuickBooks account.
For additional reference about exporting and importing data to and from QBO, you may check these articles:
In addition, you may also check our help articles for your future reference: QuickBooks Online Help articles.
As always, I'll be right here to help you if you have any other QuickBooks or exporting/importing data questions, just add a post/comment below. Wishing you continued success!
