I think the article tries to go into further depth beyond what a text editor can do on CSV files (filtering, sorting).

That said, worth mentioning CSV syntax highlighters for text editors. I’ve found rainbow csv quite helpful (https://github.com/mechatroner/sublime_rainbow_csv)

I've had pretty good experiences with both of those editing the raw files. However, neither of them give capabilities like moving columns or doing filtering. But for basic editing or viewing, they definitely work.
