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
