Assuming you have read the Excel Sheet as Datatable, we make a Clone of that Datatable like below :
OutputDT = InputDT.Clone
Where OutputDT and DT are variables of Type Datatable
Next, we use a Linq Query to Remove the Quotes at the beginning and Populate the Output Datatable using Assign Activity Below :
OutputDT = (From r In InputDT.AsEnumerable
Let ra = r.ItemArray.Select(Function(x)x.ToString.Trim("'")).ToArray
Select OutputDT.Rows.Add(ra)).CopyToDataTable()
We then Write the OutputDT to the Excel using Write Range Activity.
OutputDT = (From r In InputDT.AsEnumerable
Let ra = r.ItemArray.Select(Function(x)x.ToString.Trim("'".ToCharArray)).ToArray
Select OutputDT.Rows.Add(ra)).CopyToDataTable()
