Get the data you need without leaving Microsoft Excel
CDXStreamer is a Microsoft Excel add-in that verifies and corrects address lists, and looks up ZIP and ZIP+4 Codes, all while working entirely within your spreadsheet.
With our Excel add-in there's no need to upload or export data to another software. You can access functions through the CDXStreamer commandbar - which can be hidden when not needed - or you can just right-click anywhere in your spreadsheet. And you can easily update data with CDXStreamer custom function formulas.
CDXStreamer also provides additional data associated with ZIP+4 and Canadian postal codes, as well as U.S. Census TIGER/ZIP+4 data. All data is the latest available from the U.S. Postal Service.
