Well of course, you simply wrap whatever technique you are using in a query of all the tables - select table_name from dba_tables; assuming you have appropriate privilege. However, this will get more than just the user tables, it will get lots of system tables too, so you more likely want to limit it to certain schemata.
Of course, the more global question is what you want to do with the data. There could be different answers, depending. For example, if you are intent on actually importing to an excel spreadsheet, you could maybe use the http://www.orafaq.com/node/508 xml db and open the xml file directly with excel (never tried it, just thinking out loud). If you are keeping the data as a backup or for cloning to another Oracle database, there could be different answers. If you are moving it to another database, there could be still different answers. You're not in toyland any more, let people know what you actually want to accomplish and you may be surprised. If you use non- techniques in Oracle databases, you may get frustrated. If you try to use database-blind techniques, you may suffer. There's a huge beautiful world of database out there.
