Good points on using proper CSV tooling 100%; so that’s why the disclaimer “more often than not”

BTW I just realized that I was omitting the field separator ‘-F,’ actually.

For those pesky nested commas from top off simplistic text hat still I’d go back to sed for fun and potential profit:

sed 's/","/"\t"/g; s/^"/"\t/; s/"$//; s/,,/, ,/g' | column -t

Not elegant nor hands-off and might be missing something else; def needs the right data / volume and fiddling as we know ymmv; can get unwieldy quickly etc etc

TLDR; use column -t when applicable
