You’re most welcome, @SDM2.

Let me share some details about WebConnect and Express WebConnect.

Web Connect is a connection method in which the transaction download is initiated by visiting the financial institution's website and downloading the file containing the transaction information.

While the Express Web Connect is a one-way connection. Which communicates directly with your bank on your behalf.

You can check the available formats with your financial institution. You can choose WebConnect or Express WebConnect as long as QuickBooks Online supports the file type.

You can check this article for more information about the importing transactions with its file format: Manually upload transactions into QuickBooks Online.

For any banking queries and troubleshooting process, you can refer to this link as a reference moving forward: Help articles. I’m sure you’ll find it very helpful.

It'll be my pleasure to assist if you need more help. Have a good day.
