## What it is
A JavaScript library and CLI tool that converts JSON (including NDJSON) into CSV with column titles, supporting streaming for large datasets. This original repository is abandoned; development continues as split @2csv packages.

## Use cases
- convert  files to csv
- export  api responses as csv spreadsheets
- stream large nd datasets to csv
- convert  to csv from the command line
- flatten nested  into csv columns
- generate csv with custom delimiters and escaping

## When to choose
- you need a battle-tested JSON-to-CSV converter for Node.js or the browser (via the successor @2csv packages)
- you want both a programmatic API and a CLI
- you need streaming conversion of very large datasets

## When to avoid
- you want actively maintained software - use the successor @2csv/* packages instead
- you need CSV-to-JSON conversion
- you are not working in a JavaScript/Node environment

## Facets
- artifact type: library
- maturity: abandoned
- function: serialization, cli, parser, csv
- domain: developer-tools, files
- platform: cli, cross-platform
- tags: -to-csv, data-conversion, streaming, nd, export, data-engineering, command-line, nodejs
