This option creates a new Excel workbook with Data and CCs worksheets which are empty of data records, but otherwise identical to the original workbook.
The Data worksheet's first two rows, the header rows, will have information copied from the original workbook's Data worksheet.
The lines in the new workbook's CCs worksheet will be identical to those in the original workbook's CCs worksheet.
Note that the new workbook should be saved as soon as possible.
