Good for converting videos to audio on phone ... but then what?

Sharing via email doesnt work. Dont want to use Dropbox, because my account is strictly for business. So there is no other way for me to get the audio file off my phone or into any other app on the phone to edit the audio, or load it up somewhere for sharing.
