@ -762,6 +762,7 @@ Supported types can be implicitly converted to JSON values.
It is recommended to **NOT USE** implicit conversions **FROM** a JSON value.
You can find more details about this recommendation [here](https://www.github.com/nlohmann/json/issues/958).
You can switch off implicit conversions by defining `JSON_USE_IMPLICIT_CONVERSIONS` to `0` before including the `json.hpp` header. When using CMake, you can also achieve this by setting the option `JSON_ImplicitConversions` to `OFF`.
```cpp
// strings

In both macros, the first parameter is the name of the class/struct, and all remaining parameters name the members.
!!! note
At most 64 member variables can be passed to `NLOHMANN_DEFINE_TYPE_NON_INTRUSIVE` or `NLOHMANN_DEFINE_TYPE_INTRUSIVE`.

See [Switch off exceptions](../home/exceptions.md#switch-off-exceptions) for an example.
## `JSON_USE_IMPLICIT_CONVERSIONS`
When defined to `0`, implicit conversions are switched off. By default, implicit conversions are switched on.
??? example
This is an example for an implicit conversion:
```cpp
json j = "Hello, world!";
std::string s = j;
```
When `JSON_USE_IMPLICIT_CONVERSIONS` is defined to `0`, the code above does no longer compile. Instead, it must be written like this:
```cpp
json j = "Hello, world!";
auto s = j.get<std::string>();
```
## `NLOHMANN_DEFINE_TYPE_INTRUSIVE(type, member...)`
This macro can be used to simplify the serialization/deserialization of types if (1) want to use a JSON object as serialization and (2) want to use the member variable names as object keys in that object.
