## What it is
A small, fast, header-only C++11 library for reading CSV files with no external dependencies. It overlaps disk I/O and parsing using threads and supports header-based column mapping, custom separators, and quoted strings.

## Use cases
- parse large multi-gigabyte csv files in c++
- read csv with header column mapping
- parse tab-separated value files
- read csv files with quoted and escaped strings
- handle csv files with windows or unix newlines and utf-8 bom
- fast csv ingestion into a c++ application

## When to choose
- you need a dependency-free, single-header csv reader in C++
- you must parse very large csv files quickly
- you want compile-time feature selection to minimize parsing overhead
- you need cross-platform csv parsing with helpful error messages

## When to avoid
- you need to write or generate csv files, not just read them
- you want runtime-configurable parsing options rather than compile-time templates
- you need csv dialect auto-detection or type inference
- you are not working in C++ or lack C++11 support

## Facets
- artifact type: library
- maturity: stable
- function: parser, csv, file-system, concurrency
- domain: files, developer-tools
- platform: cpp, cross-platform, windows
- tags: header-only, csv-parsing, high-performance, single-header, c++11, data-engineering, linux, macos
