Oh! Great article and, if the evil twist of fate would force me to write an export, I hope I would remember and use .usv

But I can't agree on 'default tools' - anything bigger than 3 columns is PITA to look at and I just Ctrl+H to replace the commas with tabs or \r\n (or whatever), depending on the format. At some point 'standart tools' doesn't matter anymore, because it doesn't worth to even use them on such files; think of 'jq'.
