Hi willhenry,
Reconciling accounts can be a laborious process. The good news is QuickBooks is designed to make the process as seamless as possible for you and I'd be glad to share more information.
If you need to unreconcile an entire reconciliation at once I'd highly recommend doing it through a ProAdvisor/accounting professional with access to QuickBooks Online Accountant. They have the right tools and resources to automatically unreconcile transactions in bulk.
If you're not yet connected to an accountant and this is something you'd like to explore, feel free to search for one in your area here: Find a ProAdvisor. However, if you've got access to QBO Accountant, you can check out this article which shows you how to: Undo a client’s reconciliation in QuickBooks Online Accountant.
If you don't have access to an accountant, you can undo a reconciliation by manually editing each transaction from the register. Follow the steps below to see how you can do this:
1. Select the Gear icon on the Toolbar.
2. Under Your Company, select Chart of Accounts.
3. Locate the appropriate account for the transaction.
4. From the Action column, select Account History.
5. Identify the transaction to edit.
6. In the reconcile status column (indicated by a check mark), repeatedly select the top line of the transaction to change the status of the transaction.
Codes indicate the status of the transaction:
C - Cleared
R - Reconciled
Blank - Not cleared or reconciled
7. Select Save.
For additional tips on how to avoid undoing a reconciliation, take a look at this article: Avoid undoing a reconciliation.
