I have a horribly formated, tab delimited, “CSV” that I’m trying to clean up.
I would like to quote all the fields; currently only some of them are. I’m trying to go through, tab by tab, and add quotes if necessary.
This RegEx will give me all the tabs.
\t
This RegEx will give me the tabs that do not END with a ".
\t(?!")
How do I get the tabs that do not start with a "?
Use negative lookbehind:
(?<!")\t
