You can run and customize the Check Detail report and export it to Excel. Let me guide you how. 

1. Go to Reports from the left menu. 
2. Enter Check Detail in the Search box. 
3. Set the Report period.

5. Check the Date, Amount, Name and Num boxes. 
6. Choose Run report. 
7. Export the report to Excel.

The screenshot below shows you the third to sixth steps. 

Once done, you can save the Excel format to a .CSV file. Then, add columns to enter the Positive Pay information. After that, you can upload the file to your bank. 

Customizing reports helps you get the information that you need for your business. Also, memorizing reports lets you save them with their current customization settings. For detailed steps on how to customize and memorize them, visit these two articles below:
