Csvlint.go

Validates against RFC 4180 by default, ensuring CSV files are compatible with standard parsers and preventing common formatting errors like malformed quotes or incorrect field counts.

Supports custom single-character delimiters and lazy quote handling via the --lazyquotes flag, allowing validation of non-standard or real-world data files with configurable leniency.

Provides specific error messages with record and line numbers, such as 'Record #2 has error: wrong number of fields in line', making debugging straightforward and efficient.

Uses distinct exit codes (0 for valid, 1 for parsing errors, 2 for lint failures) to facilitate automation in CI/CD workflows or data pipelines, as documented in the examples.
