@forteller @matt It should be trivial.
I made this in 20 minutes 100% based on your screenshot, so it might not work (I'm assuming the text is tab-separated, and that the line ending is LF because you don't strike me as a Windows guy)
As it is it only accepts the content of a single file each time, so think of it as a proof of concept.
A more useful thing for you would be a bash script doing the same for an entire folder or something.
