Hello there, jimmy59.
You can download the transactions from your bank's website into QuickBooks Online using our WebConnect feature.
Take note that QBO only supports file size up to 350KB. Also, other supported formats file are Comma-Separated Values (CSV), Quicken (QFX), QuickBooks Online (QBO), and Microsoft Money (OFX).

Let me know if you need more help. I'm just around to answer them.
