Hello Luke55,
I’d like to give you some insight on this.
It is absolutely possible to export your customer information and import it
back into QuickBooks Online. However, imported lists will not replace the old
information but will add up to the existing lists on file. Having said that,
you will need to edit the customer information and merge them.
Therefore, I suggest updating your customer
information in QuickBooks Online. This way, it will be less complicated for
you.
Here’s how you edit the customer information in
QuickBooks Online:
- Click the Sales tab on the left panel and select
Customers sub-tab.
- Select
a customer.
- Click Edit.
- Enter
your changes as needed.
- Click Save.
Let me know if you need more help. I’ll
be a few clicks away.
