tilo/smarter_csv: Fastest end-to-end CSV ingestion for Ruby (with C acceleration).

SmarterCSV is a high-performance CSV ingestion and generation for Ruby, focused on fast end-to-end CSV ingestion of real-world data — no silent failures, no surprises, not just tokenization. ⭐ If SmarterCSV saved you hours of import time, please star the repo, and consider sponsoring this project. Ruby's built-in CSV library has 10 documented failure modes that can silently corrupt or lose data — duplicate headers, blank header cells, extra columns, BOMs, whitespace, encoding issues, and more — all without raising an exception. SmarterCSV handles 8 our of 10 by default, and the remaining 2 with a single option each.
