CsvHelper is a .NET library for reading and writing CSV files, with support for mapping CSV data to custom class objects. It is fast, RFC 4180 compliant, highly configurable, and runs anywhere .NET Standard 2.0 is supported.

Use cases

• read csv files into c# objects
• write records to a csv file in .net
• parse large csv files with low memory usage
• map csv columns to custom class properties
• handle non-standard csv files like excel exports
• convert csv data to strongly typed records

When to choose

• you are on .NET and need robust, fast CSV reading and writing
• you need RFC 4180 compliance or Excel-compatible parsing fallback
• you want automatic mapping between CSV files and strongly typed classes
• you need to stream large CSV files with low memory usage

When to avoid

• you are not working in a .NET environment
• you need to parse other delimited or structured formats like JSON or XML
• you need a GUI or CLI tool rather than a programmable library
