My expensed all got merged

Hello, @vaishnavi-smartl.

May I know if you're referring to the merged expense accounts? I'd appreciate it if you can elaborate more about this so I can provide you the best resolution to fix your concern. 

If you want to revert a merging process, the option to do so is unavailable. You can take a look at this article for more information about merge accounts: How to merge accounts, customers, and suppliers. 

Then, you may review your accounts to ensure they match your real-life bank or credit card statements: Reconcile an account in QuickBooks Online. 

Feel free to post a comment below if you have other questions about this. I'd appreciate any response and I'm always here if you need more help. Take care always.
