Hi Augusto;
You don't need any special add-on products to control the data and widths to the excel spreadsheet file. All you need to do is "Share" or copy the current DW Control data to a DataStore that has a DW Object inside that mirrors what your spreadsheet columns, data type & width needs to be (including headings). Then, just do a SaveAS ( ) from the DS and not the DC.
