Let's take this as a test file:
$ cat text
start|10|"20|end
"10"|"20|"30"|end
"20|"10|"30|end
abc|def|"20"|30|"end
To close all open ", try:
$ sed -E 's/^("[^"|]*)|/1"|/; :a; s/(|"[^"|]*)|/1"|/g; ta; s/|"[^"|]*$/&"/' text
start|10|"20"|end
"10"|"20"|"30"|end
"20"|"10"|"30"|end
abc|def|"20"|30|"end"
How it works
If the unclosed quote can occur in the first field, a middle field or the end field, then there are three cases to consider. Thus, we have three substitute commands:
s/^("[^"|]*)|/1"|/
If the line begins with a quote but no quote appears before the first
|, this adds the quote.
:a; s/(|"[^"|]*)|/1"|/g; ta;
If a quote is missing in a middle field, this adds it. To make sure that all such missing quotes are added, the substitute command is repeated until no more changes are made.
s/|"[^"|]*$/&"/
If the final field is missing a closing quote, then it is added.
