In a CSV file, a field surrounded with double quotes doesn't
*necessarily* contain commas, but it's *permitted* to contain commas.

For example, these are equivalent:

    one,two,"three,four"
    "one","two","three,four"

There are also rules for how to represent fields that contain quotation
marks; you might not need to worry about that, at least initially.
