+# JSON_NOEXCEPTION
+
+```cpp
+#define JSON_NOEXCEPTION
+```
+
+Exceptions can be switched off by defining the symbol `JSON_NOEXCEPTION`. When defining `JSON_NOEXCEPTION`, `#!cpp try`
+is replaced by `#!cpp if (true)`, `#!cpp catch` is replaced by `#!cpp if (false)`, and `#!cpp throw` is replaced by
+`#!cpp std::abort()`.
+
+The same effect is achieved by setting the compiler flag `-fno-exceptions`.
+
+## Default definition
+
+By default, the macro is not defined.
+
+```cpp
+#undef JSON_NOEXCEPTION
+```
+
+## Notes
+
+The explanatory [`what()`](https://en.cppreference.com/w/cpp/error/exception/what) string of exceptions is not
+available for MSVC if exceptions are disabled, see [#2824](https://github.com/nlohmann/json/discussions/2824).
