Hi 
I don't know how to do, to select and exploit data from a specific sheet in an Excel file.
I receive different excel files but always with the same name of sheets "DOC1", "DOC2", "DOC3". I want to select manualy my Excel file but select automatically the right sheet that i need (DOC3).
I started my workflow like this

I select the sheet "DOC3" but don't know how to exploit data from it to process in the container "data preparation"
Maybe i have to use macro tool ? if yes can you help me ?
Thank's a lot in advance
