## What it is
A mature monorepo of Node.js and browser packages (csv-generate, csv-parse, stream-transform, csv-stringify) for generating, parsing, transforming, and serializing CSV data. It extends the native stream API and offers callback and sync APIs with full ESM and CommonJS support.

## Use cases
- parse csv files in nodejs
- convert csv to json objects
- generate csv from arrays of records
- stream large csv datasets
- transform csv records while reading
- write csv export in a web app

## When to choose
- you need a battle-tested, feature-complete CSV parser or stringifier for Node.js or the browser
- you must process large CSV files as streams with low memory usage
- you want granular packages so you only install parsing or stringifying
- you need ESM, CommonJS, and TypeScript type support

## When to avoid
- you only need quick one-off CSV inspection in a spreadsheet tool
- your data is JSON or another structured format rather than delimited text
- you need a GUI-based CSV editor rather than a programming library

## Facets
- artifact type: library
