Thank you for posting to the Community, @lknighton.

Let me help you with your concern about exporting vendor transactions from QuickBooks Desktop (QBDT) and importing this to another platform.

In QuickBooks Desktop, you can use the Other Name report to see all transactions you've made for a vendor. Let me show you how.

1. Go to the Lists menu, then the Other Name List.
2. Find and select the vendor from the list.
3. Click Report, then QuickReports:[Other name]. I've added a sample screenshot below as your visual guide.

Since we cannot provide a specific app you can utilize when importing the transaction in bulk, you’ll want to check with our QuickBooks Desktop App store. 

In terms of importing your transaction from QBDT to your preferred third-party application, you can contact their support team. They’ll be able to assist you with the process.

Feel free to ping me here if you acquire further assistance with exporting transactions. The Community always has your back. Have a good one!
