Apache Avro is a data serialization system. Avro provides:

1. Rich data structures;

2. a compact, fast, binary data format;

3. a container file, to store persistent data;

4. remote procedure call (RPC); and

5. simple integration with dynamic languages.

Code generation is not required to read or write data files nor to use or implement RPC protocols.

This package provides the FlatBuffers serialization format for Python.

Msgpack is a library for C that implements binary serialization.

This package provides a Python wrapper library to the Apache Arrow-based Feather binary columnar serialization data frame format.

qtcsv is a library for reading and writing CSV files in Qt.

Cap'n Proto is a very fast data interchange format and capability-based RPC system. Think JSON, except binary. Or think Protocol Buffers, except faster.

LibYAML is a YAML 1.1 parser and emitter written in C.

JsonCpp is a C++ library that allows manipulating JSON values, including serialization and deserialization to and from strings. It can also preserve existing comment in unserialization/serialization steps, making it a convenient format to store user input files.

Libmpack is a small binary serialization and RPC library that implements both the msgpack and msgpack-rpc specifications.

Msgpack is a library for C that implements binary serialization.

This package provides a C library for parsing and writing CSV data.

ckdl is a C library for parsing and emitting KDL. This package also provides kdlpp, a C++20 wrapper around ckdl.

Msgpack is a library for C++ that implements binary serialization.

Libmpack is a small binary serialization and RPC library that implements both the msgpack and msgpack-rpc specifications.

JsonCpp is a C++ library that allows manipulating JSON values, including serialization and deserialization to and from strings. It can also preserve existing comment in unserialization/serialization steps, making it a convenient format to store user input files.

libnop is a header-only library for serializing and deserializing C++ data types without external code generators or runtime support libraries.

This package provides the C implementation of the varlink interface description protocol and its associated command line tool

Msgpack is a library for C/C++ that implements binary serialization. This is the legacy version that predates the split into C and C++ specific packages.

msgspec is a fast serialization and validation library, with builtin support for JSON, MessagePack, YAML, and TOML. It includes the following features:

• High performance encoders/decoders for common protocols.

• Support for a wide variety of Python types.

• Zero-cost schema validation using familiar Python type annotations.

• A speedy Struct type for representing structured data.

This package provides a C version of the reader, parser and emitter for ruamel.yaml derived from libyaml.

FlatBuffers is a cross-platform serialization library for C++, C#, C, Go, Java, JavaScript, PHP, and Python. It was originally created for game development and other performance-critical applications.

Libmpack is a small binary serialization and RPC library that implements both the msgpack and msgpack-rpc specifications.

StrictYAML is a type-safe YAML parser that parses and validates a restricted subset of the YAML specification.

Cereal is a header-only C++11 serialization library. Cereal takes arbitrary data types and reversibly turns them into different representations, such as compact binary encodings, XML, or JSON.
