CSV Escape / Unescape

Escapes or unescapes a CSV string, removing characters that could break parsing. If a value contains a comma, newline, or double quote, it's enclosed in double quotes (e.g., "Newline\n"). Any double quote is escaped with another double quote (e.g., "The quote "" is escaped"). This tool ensures CSV content is properly formatted for data import, spreadsheets, and applications that rely on clean, valid CSV structures.
