You don't need to manually adjust the fields in your QBO file to upload in QuickBooks Online (QBO), VBPB. I'll share more details about this below.

Before we start, I'd like to verify your bank's name and if you encounter an error message while trying to upload transactions in QBO. This way, I can check for any product investigations and provide you with the appropriate fix.

The QuickBooks Online data (QBO) is already formatted specifically for QBO. Thus, you should be able to upload it directly into your account even without making any adjustments to its fields.

Before you upload, review the QBO file and make sure it's in the correct format. Then, please note that the maximum file size is 350 KB. If the file is too big, shorten the date range and download transactions in smaller batches.

Once everything is all set, I'd encourage you to reconcile your accounts regularly (every month) to monitor your income and expenses and detect any possible errors accordingly.
