edit contacts on PC?

[samurai1200]

Searching the forums for this is a little tricky...

I recently switched from VZW (VX9900 aka EnV) to Sprint (HTC TP). I had my sprint store transfer over all my contacts, but there were problems:

1. All contacts were duplicated
2. all contacts are listed as "Remaining_words_in_contact, First_word"
i.e. "Smith's Cell, Bob"

I know this problem can be fixed in-phone by changing the "File As:" line, but i dont want to do that for 200 contacts =(
I also do not want to delete every other contact (remove duplicates) by hand within the phone.

Is there anything I can use within Windows to edit my contacts by hand? I'm sorry if there's an obvious answer to this, I'm just not finding it...
