Best way to serialize to a delimiter, without having that delimited in a string value

Good afternoon Cribl people! I'm trying to find the best way to serialize to a delimiter, while removing the risk of having that delimited in a string value.If we serialized to JSON, string data types are put in quotes, and integers aren't. We're trying to do the same for delimited format (e.g., CSV) - encase strings in quotes, and not integers. We believe this will help Splunk parse, because it's expects a string when it reads a double quote.
