You won't be able to export the column labels in Quik Reports DOS, but you can with Quik Reports for Windows, with a number of different formats (Excel, CSV, etc).

Unfortunately, macros and their field references are not updated by Quik Reports, and would have to be manually edited or relearned. Quik Reports 6.5A had the field references changed so that they could be unique. Prior versions of Quik Reports had occasions where the same reference was more more than one field.
