## What it is
League CSV is a lightweight, framework-agnostic PHP library for reading, writing, filtering, and converting CSV documents. It offers a straightforward API with memory-efficient streaming, query features, object mapping, and conversion to JSON, XML, or HTML.

## Use cases
- parse csv files in php
- export database table to csv
- import csv records into a database
- convert csv to json or xml
- filter and query csv rows
- stream large csv files efficiently
- generate downloadable csv from php

## When to choose
- you work in PHP and need robust CSV parsing or writing beyond native fgetcsv
- you need memory-efficient handling of large CSV files
- you want to map CSV records to PHP objects or DTOs
- you need to convert CSV to JSON, XML, or HTML

## When to avoid
- you need a spreadsheet library with formula support like Excel files (use PhpSpreadsheet)
- your project is not in PHP
- you only need trivial one-line CSV parsing already covered by native PHP functions

## Facets
- artifact type: library
- maturity: active
- function: parser, serialization, data-science
- domain: files, developer-tools
- platform: php
- tags: csv, csv-reader, csv-writer, data-conversion, php-library, data-engineering
