## What it is
A fast, comprehensive CSV parser for Node.js, browsers, and the command line that converts CSV to JSON or column arrays. It supports streaming/async parsing, RFC4180 compliance, and extensive parsing configuration options.

## Use cases
- convert csv file to json in nodejs
- parse large csv files with streaming
- command line csv to json converter
- parse csv in the browser
- process csv rows asynchronously from a url
- convert csv string to row arrays

## When to choose
- you need high-performance CSV parsing for millions of rows
- you want one parser usable in Node.js, browser, and CLI
- you need streaming or async line-by-line processing
- you need strict RFC4180 compliance and configurable parsing

## When to avoid
- you need to write CSV files rather than parse them
- you work outside the JavaScript ecosystem
- you need full ETL pipeline features beyond parsing

## Facets
- artifact type: library
- maturity: active
- function: parser, serialization, csv, cli, streaming
- domain: developer-tools, files
- platform: browser, cli, cross-platform
