## Use AI to customize how property names are serialized

You can use AI tools, such as GitHub Copilot, to apply patterns of changes to how your code serializes.

Suppose your class declaration has properties that follow `PascalCasing`, and the JSON standard for your project is `snake_casing`. You can use AI to add the necessary [[JsonPropertyName]](xref:System.Text.Json.Serialization.JsonPropertyNameAttribute) attributes to every property in your class. You can use Copilot to make these changes with a chat prompt like this:

```copilot-prompt
Update #ClassName:
when the property name contains more than one word,
change the serialized property name to use underscores between words.
Use built-in serialization attributes.
```

Here's a more complete version of the example that includes a simple class.

```copilot-prompt
Take this C# class:
public class WeatherForecast
{
public DateTime Date { get; set; }
public int TemperatureC { get; set; }
public int TemperatureF { get; set; }
public string? Summary { get; set; }
public int WindSpeed { get; set; }
}
When the property name contains more than one word,
change the serialized property name to use underscores between words.
Use built-in serialization attributes.
```

Review Copilot's suggestions before applying them.
