About CSV Conversion
CSV (Comma-Separated Values) is a simple format for storing tabular data. While widely supported, different applications often need data in other formats like JSON for web APIs, XML for legacy systems, or HTML for display.
This converter handles standard CSV features including quoted fields (for values containing commas or newlines), various delimiters, and optional header rows. The parser follows RFC 4180 standards for reliable conversion.
