Oracle: Spool to Excel from SQLPlus

Spooling the output from SQLPlus to log file is often in unreadable format.

To Spool SQLPLus output to Excel (.xls) file, the trick is to turn On "MARKUP HTML"

SQL>set markup html on
SQL>set feedback off

SQL>spool c:\test.xls

SQL>select * from user_objects where rownum <= 20;
SQL>spool off

SQL>set markup html off
