+# Parsing A CSV With Quotes In The Data
+
+If a CSV contains unescaped quote characters--like you might find in a CSV full
+of measurement data--then Ruby's
+[CSV](https://ruby-doc.org/stdlib-2.6.1/libdoc/csv/rdoc/CSV.html) library will
+be unable to parse it.
+
+Here is what happens with a line of CSV about some lumber:
+
+```ruby
+> require 'csv'
+> CSV.parse_line('oak,2",4"')
+CSV::MalformedCSVError (Illegal quoting in line 1.)
+```
+
+However, we can enable some more lenient, liberal parsing of the data with the
+`liberal_parsing` argument.
+
+```ruby
+> require 'csv'
+> CSV.parse_line('oak,2",4"', liberal_parsing: true)
+=> ["oak", "2\"", "4\""]
+```
