Convert Google Base Feed in .txt for Amazon Product Ads

Hi Community,

Sorry, I posted this somewhere else, so if moderators want to remove previous post...

I need to submit a Google Base Feed to Amazon for Product Ads but they want it in .txt format. Is there a way to do this easily? Or an extension that can do it? I've found an extension but it's really outdated (2012) and it doesn't even support my version of OC.

Thanks!
