C++26 reflection could simplify JSON handling in C++

What happened and what to do
Published on March 25, 2026, the CppCon 2025 talk covers JSON serialization and deserialization using reflection features proposed for C++26 and the standard library. The approach presented avoids macros and manual mapping of data structures. The talk also addresses possible effects on JSON processing and C++ performance.
A company maintaining C++ services could evaluate the approach in a prototype, compare maintenance effort, and measure performance with representative workloads. Before adopting it, the team should check compatibility with the standard and the compilers used in its environment, and establish tests to preserve the behavior of serialized data.
How the consultancy can help
Wendelmaques can diagnose how your environment uses JSON and C++, define a scoped prototype and evaluation, and implement an appropriate solution, including tests and monitoring when needed.
