What would you like to do?

Describe your file
Tell us what your file contains and how it's laid out. It is read on your own computer and never uploaded.
1. File layout

Matching uses exact full name and full address. Other columns help you check results, and anything you don't need is ignored and never leaves your computer.
3. Your columns, as we read them
Wrong column? Pick the right one from the list. You can also download a layout template.
