I have exempted performance tests from execution for now. They are too
expensive to execute automatically. Besides, I have intentions to migrate to
BenchmarkDotNet at some point.

Build status


KBCsv is an efficient, easy to use .NET parsing and writing library for the CSV (comma-separated values) format.


CSV is a common data format that developers need to work with, and .NET does not include intrinsic support for it. Implementing an efficient, standards-compliant CSV parser is not a trivial task, so using KBCsv avoids the need for developers to do so.


The easiest way to get KBCsv is to install via NuGet:

Install-Package KBCsv

Or, if you want the extensions:

Install-Package KBCsv.Extensions

Data-specific extensions are available as a separate package for .NET 4.5 (the other packages above are portable):

Install-Package KBCsv.Extensions.Data


using (var streamReader = new StreamReader("data.csv"))
using (var csvReader = new CsvReader(streamReader))

    while (csvReader.HasMoreRecords)
        var record = csvReader.ReadDataRecord();
        var name = record["Name"];
        var age = record["Age"];

Please see the documentation for more details.
