Here's a script that takes any query and presents the data in tabular format.

set serverout on size 999999
set verify off
declare
p_query varchar2(32767) := q'{&1}';

    l_theCursor     integer default dbms_sql.open_cursor;
    l_columnValue   varchar2(4000);
    l_status        integer;
    l_descTbl       dbms_sql.desc_tab;
    l_colCnt        number;
    n number := 0;
  procedure p(msg varchar2) is
    l varchar2(4000) := msg;
  begin
    while length(l) > 0 loop
      dbms_output.put_line(substr(l,1,80));
      l := substr(l,81);
    end loop;
  end;
begin
    execute immediate
    'alter session set nls_date_format=''dd-mon-yyyy hh24:mi:ss'' ';

    dbms_sql.parse(  l_theCursor,  p_query, dbms_sql.native );
    dbms_sql.describe_columns( l_theCursor, l_colCnt, l_descTbl );

    for i in 1 .. l_colCnt loop
        dbms_sql.define_column(l_theCursor, i, l_columnValue, 4000);
    end loop;

    l_status := dbms_sql.execute(l_theCursor);

    while ( dbms_sql.fetch_rows(l_theCursor) > 0 ) loop
        for i in 1 .. l_colCnt loop
            dbms_sql.column_value( l_theCursor, i, l_columnValue );
            p( rpad( l_descTbl(i).col_name, 30 )
              || ': ' || 
              l_columnValue );
        end loop;
        dbms_output.put_line( '-----------------' );
        n := n + 1;
    end loop;
    if n = 0 then
      dbms_output.put_line( chr(10)||'No data found '||chr(10) );

You can easily just manipulate this to output the columns as CSV, or any other format you like.

However, don't forget that you could always just use 'sqlcl' on the server, and just run queries as:

select /*csv*/ * from table

or on modern versions of SQLPlus you can do:

SET MARKUP CSV {ON|OFF} [DELIMI[TER] character] [QUOTE {ON|OFF}]
