Any good tools to compile a list of contact info into something that can be imported to both iphone and Android contact lists?

Nearing the end of nursing school - we've been exchanging a lot of contact info in our class chat, but it's becoming a clusterfuck of that mixed with other random messages...

I'm wondering if pull all that data into its own list, if I can then convert that list into Google Calling Cards or something that can be loaded in bulk onto my and my classmate's phones.

There are around 100 of us, and we've got a pretty even split of iphone and android users... idk if Calling Cards or iphone's equivalent are compatible with the other OS.

I could make the contact list individually on my own phone, but sharing it with my classmates is the main goal, and it'd be way less tedious to do this on my desktop and import it later... but I'm not aware of any way to actually do that.

Open to all suggestions!
