A have positive pay set up with our bank. Is there a way for me to transfer my check run information in a .csv ( comma delimited) format out of QBO to the bank?

Thanks for posting to the Community, @steven-smith.
 

Yes, there's a way to transfer your check run information in a CSV file format out from QBO.

Let me show you how:

1. Go to the Expenses menu and then select Expenses.
2. Click the Filter drop-down list.
3. Choose Check on the Type of transaction.
4. Hit Apply.
5. Click Export to Excel and then open the exported file.
   You should see something like this. This is a .xls file type format. We can now proceed to convert it as a comma delimited file (.CSV)
   
6. Go to the File menu and then select Save as.
7. Change Save as type to comma delimited.

There you have an output of the checks in a CSV format.

I'll add this article as your reference on how to export customer information from QBO: Export customer data to Excel.
