About
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.
Problem
Traditional CSV files lack type information, have ambiguous quoting rules, and require consumers to guess or infer data types, leading to parsing errors and data loss.

developers and data engineers working with tabular data
How it works
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.
