## What it is
Rapidcsv is an easy-to-use, header-only C++11 CSV parser library for reading and writing CSV files. It supports column/row headers, typed column access, and works across Linux, macOS, and Windows.

## Use cases
- parse csv files in c++
- read a csv column as a vector of floats
- write csv files from c++
- handle csv files with column and row headers
- parse utf-8 or utf-16 csv data
- drop-in single-header csv parsing for a c++ project

## When to choose
- you need a lightweight, header-only CSV parser in C++11 or later
- you want simple typed access to CSV columns and rows
- you need cross-platform CSV support without external dependencies

## When to avoid
- you need high-performance parsing of very large or malformed CSV files
- you need full RFC 4180 edge-case compliance or streaming parsing
- you are working in a language other than C++

## Facets
- artifact type: library
- maturity: stable
- function: parser, csv, serialization
- domain: files, developer-tools
- platform: windows, cpp, cross-platform
- tags: header-only, csv-parser, c-plus-plus-11, utf8, utf16, data-engineering, linux, macos
