# NavigationPageConverter

> Handles JSON conversion for navigation page items that can be either strings or GroupConfig objects.

## Definition

**Assembly:** Mintlify.Core.dll

**Namespace:** Mintlify.Core.Converters

**Inheritance:** System.Text.Json.Serialization.JsonConverter\<object>

## Syntax

```csharp theme={"dark"}
Mintlify.Core.Converters.NavigationPageConverter

## Summary

Handles JSON conversion for navigation page items that can be either strings or GroupConfig objects.
