xls script should work with excel 2007 as well, but as snapper uses dbms_output for output (instead of returning a cursor resultset in table form) then the html wouldnt be generated correctly anyway.

Use snapper’s pagesize=-1 / pagesize=0 option and trace option (to trace into a file) and then load it to excel. I have deliberately formatted snappers output in a CSV fashion (commas separate columns) for exactly this reason.

Tanel,

its possible the output to be imported as CSV or TXT? I thought using your xls script is possible but at the moment doesnt work in Excel 2007
