Parsing a CSV file using gawk

Question

How do you parse a CSV file using gawk? Simply setting FS=\",\" is not enough, as a quoted field with a comma inside will be treated as multiple fields.

You can use a simple wrapper function called csvquote to sanitize the input and restore it after awk is done processing it. Pipe your data through it at the start and end, and everything should work out ok:

before:

gawk -f mypgoram.awk input.csv

after:

csvquote input.csv | gawk -f mypgoram.awk | csvquote -u

See https://github.com/dbro/csvquote for code and documentation.
