FUNCTION

# gtv.to\_json

```signature
pure function to_json(): json
```

Convert this GTV to a JSON value.

Big integers are serialized as JSON numbers. Note that when deserializing back with
`gtv.from_json()`, small big integers (within standard integer range) will become regular
integers, and large big integers cannot be deserialized (will cause a runtime error).

**Returns**

a JSON value equivalent to this GTV

Since 0.9.0
