Ryan would like to copy a list of contacts from a colleague into his personal address book. The list of contacts is contained in a simple text file. What should he do first?

A plain text file may not be arranged in a format that an address book can import as contacts. Ryan should first organize the contact information into comma-separated values and save it as a CSV file, which is the standard format for importing contact lists. Exporting to a .pst file is not the needed first step.
