If you already have guest details (for example in an email or organizer address book, spreadsheet or text file) you can import the data directly into PerfectTablePlan, rather than re-typing it.
PerfectTablePlan can import information in 4 major formats:
•Excel™ .xls/.xlsx - Excel's proprietary format.
•CSV (Comma Separated Value ) - A text file that can be produced by Excel (select File>Save As and choose .csv as the file type) and many other types of applications. Columns and rows are delimited by commas and carriage returns, respectively. " and , characters are quoted.
•Delimited text data - A text file with the user's choice of delimiters (separators). Many applications can produce data in this form. CSV is a special form of delimited text data.
•vCard file - vCard files be exported from most applications with address books, including Outlook, Palm Pilot desktop and the Apple Mac Address Book.
As a simpler (but less flexible) alternative to importing you can also use the 
Quick Add Guests window.
