# Json Format

> Working with Json data in Orbital

Source: https://orbitalhq.com/docs/data-formats/json

JSON is the default format for reading / writing data to/from Orbital, so requires no special customization.

## Using jsonPath() references

**Warning: Deprecated**
Using the `by jsonPath()` tag is deprecated.

  Field names in the model are now used to match elements and attributes
 

It's possible (but discouraged) to use `by jsonPath("")` references to declare a field:

```taxi
model Person {
  firstName : FirstName by jsonPath("$.fName")
}
```
