Once a list is downloaded it can be found in the "My Recent Downloads" tab located in the upper right-hand corner of the Target page. Clicking on the tab will give you access to the file after it has completed processing. You will know that it has completed by the red indicator bubble appearing, and the file itself will be listed in bold with the status reading "Complete."
To open your file, simply click on the number of records within the file line item. It will then open in Excel as a CSV file.
All files you have downloaded can also be found on your Target dashboard under the "Project History" module for your convenience.
