How to import a CSV file into Palm's address book:
Let's say I have an Excel spreadsheet on file or I've created one:
You'll need to save it in CSV format:
Now go into your palm Desktop software. Select File -> Import...
Again, under the "Files of type:" select "Comma Separated (*.csv, *.txt)" and open the file you just saved (PalmAddress.csv).
You should see a window similar to this (if you are running the same version of Palm Desktop - this is version 3.1)
Follow the directions to match up the available fields in your CSV file. After aligning them, my window now looks like this:
Press the [OK] button and Viola!
Note: Your heading will appear as an address record in your palm. Just remove it. It is nice to have during the import though.
