Parse a csv file where field values are enclosed by quotation marks and contain carriage return #eg35

Here is a csv file. Its 3rd column contains strings of a special format – they are enclosed by double quotation marks and some occupy multiple rows (which means they contain carriage return).

Task: Use Java to reorganize the csv file as a standard two-dimensional table.

Write the following SPL statement:

=file(""data.csv"").import@tcoq().run(description=replace(description,""\n"",""""))

import() function parses the csv file as a two dimensional table; @t option enables importing the 1st row as column names, @c option enables using commas as the separator, @o option handles the unescaped carriage return in lines, and @q option enables removing quotation marks at both sides before parsing. run() function modifies the two dimensional table and return the modified table.
