Is there a tool that converts UWP/Windows 10 XAML to Xamarin Forms XAML?

I have developed some apps that run on UWP. Now I want to convert them to Xamarin Forms since Windows 10 mobile is pretty much dead.
As far as I know there are quite a lot of differences between Windows 10 XAML and Xamarin Forms XAML. For example, StackPanel (on UWP) vs StackLayout (on Xamarin Forms)

Is there a tool that can convert UWP XAML to Xamarin Forms XAML?
