Super CSV
A new standard for data — type-safe, lossless, human-friendly CSV.
Super CSV is a proposed new CSV format specification that adds type declarations, enums, lists, arrays, datetimes, and comments directly to CSV headers. It aims to make tabular data self-describing and unambiguous, eliminating the guesswork of traditional CSV parsing. The format supports both a human-friendly mode with whitespace and comments and a strict machine-first mode for high-throughput streaming.
Super CSV extends the CSV header row with type annotations and schema definitions, allowing parsers to enforce types, enums, lists, and arrays at parse time without external schema files.
