This reminds me of an Arabic client who wanted both English and Arabic version of the app. I sent him a spreadsheet with 2 cols, with English on one column, and another empty column where I expected him to fill the Arabic translation.

He replied with a plaint .txt file with a couple of Arabic lines in it, with a message saying "I translated some of those text from your excel sheet, please go ahead and use this text, I will send the rest by tomorrow". Nobody understood which translated to which.
