Could you be a little more specific on just what you want to do?
Are you concerned about quotation marks embedded in a string?
   In that case, you can use the Replace function to replace them with a
blank string.

OTOH, if you're concerned that you see string values reported with quotation
marks around them, that's so you can tell where the string value begins and
ends.  Those quotation marks aren't really part of the value.
