I really don't like how you're putting words in his mouth. He said nothing to suggest that he felt Excel was inadequate for editing CSVs. That's your opinion. And, it's not exactly streamlined, but it's good enough that Microsoft will suggest using it for that purpose. https://support.office.com/en-us/article/Create-or-edit-csv-...

I misread the author - thought it was someone who'd been posting elsewhere in the thread about Excel (which does have CSV issues for days).

Mea maxima culpa.
