CSV Stringify

csv-stringify is a JavaScript library designed to convert data records into CSV (Comma Separated Values) formatted text. It primarily implements the Node.js `stream.Transform` API, allowing for efficient processing of large datasets by handling data in chunks rather than loading entire files into memory. The package also provides convenient synchronous and callback-based APIs for simpler use cases. First released in 2010, it boasts a mature codebase, comprehensive test coverage, and a focus on scalability and customizability, supporting various delimiters, quotes, escape characters, and headers. It is currently at version 6.7.0 (as of early 2026), indicating active maintenance and consistent updates. It is often used as part of the broader `node-csv` ecosystem alongside `csv-parse`, `csv-generate`, and `stream-transform` to build complete CSV processing pipelines.
