UPDATE Nov 10,2009:Convert your files online now @ onix-files.com We're live! yay!
I'm still in the process of building the online conversion process for onix-files.com, but it should be ready this weekend.
I've been getting quite a few requests for ONIX to CSV conversion (and a few the other way), I can run a quick conversion for you for $10 for a single file if you are in a hurry. Paypal will work, just email me: Convert ONIX to CSV. If you need another format, just ask.
Again, the self-serve system will be available by Monday October 26, but I'm willing to run a conversion for someone who needs it right away.
