How can I generate an invoice in cXML format?

I'd be glad to provide some additional info about the QBXML format, @by4.

If you're trying to save the transaction data from a report in QuickBooks Online (QBO), we can only export them as Excel or PDF. 

I'd suggest looking for a third-party app that can integrate with QBO. This way, you'll have an option to export the data in XML format. Just go to the Apps menu or through the external QuickBooks App Center.

Here’s how:

1. Go to this link: https://quickbooks.intuit.com/app/apps/home/.
2. Choose the US flag in the Country drop-down.
3. Enter Export in the Search box. 
4. Select the app to open its profile. View the other apps by selecting them. 
5. Choose the right app for your business. 
6. Click Get the app now. 

I've added an article to learn more about the data and the lists you can export from QBO: Exporting Reports, Lists, And More. 

I'm always a few clicks away if you have any more questions or concerns. Have a safe and productive rest of your day!
