You can use another delimiter instead of comma perhaps - like vertical bar ?

Love that option. We often have descriptive data where commas slip in, so we might be using vertical bars as delimiters as SOP in the future.
I solved my immediate problem using the double quotes and my data loads and works as expected. Thanks again for all of the responses and I also plan to use alternate delimiters in the future too.
I started out only needing to solve my problem, but ended up gaining some extra wisdom in the process.
