I noticed 1Password translates the headers into my locale, but keeps the original ones between parentheses, so I parsed the file to strip the translations and keep the original.

I actually removed the few remaining extra (empty) columns which were in my locale only (probably new in 1Password 7), but all the rest remains well formed.
