Hello Guys,

![image|211x72](upload://lU2IA2yXsfYo1onYDEKTGNYW3sp.png) 

and try to open it in:

uipath 2019
Studio 2018.2.2
Entreprise edition

but i had the following error:

data at the root level is invalid line 1 position 1

Hello, has anyone an idea about how to handle this?

@abdel

Can you share your .xaml file? Also the picture you attached in the original post isn’t displaying, at least for me.

ÉTAPE 4.xaml (11.5 KB)

Main(Autosaved) has thrown an exception

Source: System.Xaml

Message: Cannot set unknown member ‘UiPath.Excel.Activities.ExcelReadRange.PreserveFormat’

This sort of thing is usually because you need to update your UiPath packages, have you tried this?
