Hi @PowellDecor,

I'll provide the file types compatible for bank transaction upload in QuickBooks Online (QBO).

These are CSV, QBO, QFX, and OFX files. If your online bank doesn't offer these type of files for their transactions, you'll have to look for a third-party app that can convert their files.

You can also visit this page: QuickBooks Apps Store. It's a complete list of third-party apps that you can sync to QBO and help with the conversion process. 

Once done with this process, see this article: Manually upload transactions into QuickBooks Online. It's a step by step guide on how you can import bank transactions to your QBO company. 

Have other questions in mind? Place them below, and I'll get back to you.
