Validation list with ODBC and Excel

[jakub.markowski93]

I see in Batch types there is a setting called Validation lists which allows to use Odbc to connect to database. In my case I want to use Excel file.  I use following connection string: 

Driver={Microsoft Excel Driver (*.xls, *.xlsx, *.xlsm, *.xlsb)};Dbq=C:\Users\JMarkowski\Desktop\test.xlsx;

When I test connection, it says it's successful, however when I go to document form definition I don't see there any data. 

Can you please implement this functionality working with Excel in Decipher?
