Looking for mod/plug-in to mass update Profile Field by CSV

I am looking for a plug in that lets me mass update a Profile Field with a CSV.  

Pairs of :  email, value 

The value will be unique codes, something like: 678KjHDf

Do you foresee any problems with this? Are there unintended consequences or risks I am not considering?

Our community is on CIC.

We are looking to pay someone to build this, and happy to make it available to anyone that could use it however that works.

Thanks
JM
