I need a freelancer to write a desktop application or a web page host that will pull name
and address data from an Excel spreadsheet ([url removed, login to view] format), do phone number
look ups on [url removed, login to view], and compile the corresponding phone numbers into a new
column in a copy of the input spreadsheet (in .CSV format).
This application should only pick out a phone number when the look up yields an exact match for the name, street address, town, and state OR when the look up yields a single number for the name, town, and state. When there are multiple listings for the same name, town, and state, the application should return a blank.
