Thanks in advance! Am I able to export my customer information to excel, make necessary changes and import again into quickbooks online?

Hi there, mahalo. Allow me to help you export and import customer information in QuickBooks Online (QBO).

Yes, you can export customer information to Excel, make necessary changes, save the file in a required format, and then import it back to QBO.

If you want to export customer data from the Customers page, you can export information such as Name, Company, Complete Address, Phone number, Email Address, Attachment, Open balance:

1. Go to the Sales tab and select Customers.
2. Look for the icon located next to the Print icon and click on it.
3. Then, it lets you export to Excel.

Before importing customer information, carefully review and verify the data. Save the file in CSV, XLSX, or Google Sheets format and ensure files are under 2MB or 1000 rows. If the file is larger than the limit, let's split it into multiple files.

If you're ready to import, follow these steps to proceed:

1. Sign in to your QBO account.
2. Go to the gear icon and select Import Data.
3. Select Customers.
4. Choose the file you saved earlier, and follow the on-screen steps to import.

Thank you so much for this information Carl, I think it will save me a lot of time updating my customer accounts. I just wanted to ask for clarity that changing this information won't affect the sales history for existing customers. I assume not as long as we don't change the customer name? 

Hello there, mahalo111.

Allow me to jump in. Yes, certainly you are right that changing information for a customer account in QuickBooks Online will not affect existing customer sales history as long as the customer name remains unchanged.

Moreover, please note that when importing contacts from a spreadsheet, it is important to ensure that each entry in the Name field is unique. This applies to files exported from Google Sheets, Excel, and CSV formats. It is essential to avoid having multiple vendors, customers, or employees with the same name, as this can cause confusion and errors in your contact list.
