Extracting Data to Excel using only SQL*Plus

Lately I had to quickly extract some data from Oracle DB to Excel. There are a lot of tools that can do that, ex. Toad or SQL Developer, but I had only access to SQL*Plus. Additionally I was on Windows machine and database was in UTF8. And extracted data was also using many different languages.
Here are steps I used to archive my goal:

1. start command line (CMD)
2. set NLS_LANG variable
   

   set NLS_LANG=.UTF8

3. start sqlplus and log to database
   

   sqlplus user/pwd@db

4. set long line size and avoid paging
   

   SQL> set linesize 4000
   SQL> set pagesize 0

5. set markup html in sqlplus
   

   SQL> set markup html on spool on

   
   It is important to use spool on clause, as it adds html header to spool file when spooling is started
6. start spooling
   

   SQL> spool a.html

7. run your query
   
8. turn off spooling
   

   SQL> spool off

9. open file in Excel

I've tested this procedure on Oracle 10g R2 (10.2.0.1 and 10.2.0.3) and Excel 2003
