I've just got an Android handset and the import of the SIM contacts from my old phone has left them in a mess; lack of capitalisation, funny character substitutions, odd delimiters etc. I have exported the contacts list as a vcf and while I could manually edit this file, I was really after a desktop app that could do formatting, search & replace etc.

There are Android apps that do this but, as much as I like the phone's UI, the prospect of sorting hundreds of contacts via it doesn't exactly fill me with joy.

A quick Google just threw up lots of questionable download sites, hoping someone can suggest a lightweight alternative
