I want to ensure this is taken care of, @miranda-bergquis.
I'd be happy to help you export your bank reconciliation in QuickBooks Online (QBO). Before I do, can you elaborate more on your concern? Are you trying to export a bank reconciliation page before reconciling it? This way, I can give you the right steps on how to do so.
However, if you're trying to export a reconciliation report, currently, we're unable to export it. Though, we can only print or save it in .PDF format.
You can also manually export the data, check this link for the steps under How to export a reconciliation report to Excel: How do I view, print, or export a reconciliation report?
I'm also sharing these handy articles about the reconcile workflow and reports for your reference. Feel free to check the links below:
Don't hesitate to drop a comment below if you have other questions. I'm more than happy to help. Take care!\
