Text::ParseWords::quotewords will work given the few sample lines of input you have provided, but it makes certain assumptions about your data format:

• that "spaces" can be escaped using backslash (ie: \ ) and thus considered a "word character".
• that a double-quote can be escaped using a backslash (ie: \" and thus considered a "word character".

If these assumptions don't match your data, you might want to take a look at Text::CSV_XS ... the constructor allows you to specify attributes like: what quote character to use, what seperator character is, what escape character to use.
