## Mappings and Type Conversions for FolkerKinzel.CsvTools (RFC 4180)

[Project Reference](https://folkerkinzel.github.io/CsvTools.Mappings/reference/)

This package allows:

- analyzing CSV files and CSV strings (delimiter, header row, column names, text encoding, and required options for reading non-standard CSV)

- retrieving the appropriate method arguments for exchanging CSV data with Excel

- serializing and deserializing collections of any data type 

- serializing and deserializing DataTables

- to do things easily and with just a few lines of code. In addition, the package also provides the means to write high-performance code:

	- It allows you to parse ultra large CSV files because only one row of the file has to be in memory at a time.

	- It makes the fields of the CSV file available as `ReadOnlyMemory` instances. This avoids the allocation of numerous temporary strings.

	- It allows to parse value types without any boxing and unboxing and (when using a modern .NET version) without any allocation of temporary strings.

	- The `CsvOpts.DisableCaching` option allows reusing the same `CsvRecord` instance for each parsed row of the CSV file. This can avoid further allocations.

(See [benchmark results](https://github.com/FolkerKinzel/CsvTools.Mappings/tree/master/src/Benchmarks/results) and the associated [benchmark code](https://github.com/FolkerKinzel/CsvTools.Mappings/tree/master/src/Benchmarks).)
