Notes:
Importing and exporting CSV data files with quote characters can cause problems.
Quotes are used to qualify (enclose) strings along with delimiters (field separators) i.e. tab or comma characters in CSV data files.
Tip: Use Part's Excel Import and Export features to avoid CSV file related issues.
That's it !
