MegaSign - Commas in CSV data file to be merged with agreement

We are using MegaSign to merge data from a CSV file into a Word document.  We would like to include commas in the one of the columns of data in the CSV file.  Would having commas in the CSV file create any issue with the output of merged documents or any other functionality of  MegaSign? Is there a "best practice" with regard to having commas in the data that is being uploaded into MegaSign?
