reflect-cpp is a C++20/C++26 library for fast serialization, deserialization, and validation using reflection, comparable to pydantic or serde. It supports many formats out of the box including JSON, YAML, TOML, Avro, Parquet, msgpack, CBOR, and BSON, and also provides CLI argument parsing.

Use cases

• serialize C++ structs to JSON and back
• parse and validate configuration files in YAML or TOML
• read and write Parquet or CSV tabular data
• deserialize API responses into typed C++ structs
• parse command line arguments into structs
• reduce boilerplate for data exchange between C++ components

When to choose

• you need pydantic/serde-style serialization in modern C++
• you want one library supporting many serialization formats
• you need type-safe validation with clear error messages
• you want fast serialization performance

When to avoid

• you are stuck on pre-C++20 compilers
• you need a minimal JSON-only parser with no reflection overhead
• your compiler is not GCC 11+, Clang 14+, or MSVC 17.8+
