I cannot remember how often, when I worked in 'enterprise software', we were sent CSV files by companies, and they were completely broken after someone 'simply edited' them with a 'standard editor'. More than a 1000x for sure over the years. Worse; most 'non computer people' cannot get them imported into a spreadsheet properly (for whatever reason; usually it just puts everything in one field or column, people curse and give up), so they have to edit them in Notepad or worse, in MS Word and then send them back. Not really seeing the beauty I guess.
