Any number of ways. Depends on what you are doing with the "export". Don't know? Then you're probably actually looking for a "backup". Then you can "restore" or "import" or "install" ....

If you really need to export the data as a file...

Export it from the database as XML. The number of columns is only limited by the number of columns you can have in Excel, and Excel can real XML files.

If you can, create a cdata connection in excel that will pull the data from the database without the intermediate "create a file" step.
