Can we convert XLS to IPD?

Topic. I have been using ABC Amber Blackberry Converter and it is able to convert IPD files to XLS. But if I want to add contacts from a separate XLS file (not originally from an IPD) to it and save/convert it back to an IPD... how do I do that?

Because there doesn't seem to be any programs out there that convert XLS to IPD, although there are a few that do the opposite. Playing around with these IPD backup files is annoying...

If you are using Outlook on your PC, you can import contacts into Outlook from the XLS file and sync to your BlackBerry. The new contacts will be included in the IPD the next time you make a backup.

Was a bit challenging to figure out the correct method to do it but I finally got it. Thanks a ton for the help!

And thank god for Excel and comma separated values.
