The `CSVStringify` function does not handle potential errors that may occur during the stringification process. It's recommended to wrap the `stringify` function call in a try-catch block to handle any exceptions and provide a more graceful error handling.

The escape handling in the `CSVToMarkdown` function could lead to incorrect data representation. The '<' and '>' characters are replaced with 'lt;' and 'gt;', which are not valid HTML entities. They should be replaced with '&lt;' and '&gt;' respectively.
