I came across this little gem of a utility during a futile attempt to leave my laptop at home while traveling. One main problem with doing so is that I don’t have ready access to all my contacts when I am abroad. I keep everything in Apples Address Book app. and there is no really convenient way to sync this with Googles Gmail. A to G solves this problem and it’s free!
A to G is a simple, free utility for Mac OS X that exports your Apple Address Book contacts into a Gmail-readable text file. Once exported, simply click Import in the Contacts section of your Gmail account, choose the file you exported, and you’re done!
A to G will bring over your contacts’ phone numbers, email addresses, physical addresses, companies, job titles and notes so that you can have info you need wherever you have Gmail.
