importing excell sheets into an database

How do you import a excell sheet into a database( Oracle)

Is there a function for the conversion?

don't know any conversion function, try to export as ; separated text file, then read in..

When i am trying to convert excell to oracle, i Found the DTS Tool.

1)First U Convert Excell Sheets into Oracle
Through DTS Tool(Default in SQL SERVER DATABASE) , There was options from which Source and Target.

eg: sql server, excell, oracle, .....

If the source was not transferred exactly to Destination then try this option.

2)First U Convert Excell Sheets into Microsoft SQL Server Through DTS Tool and Then Convert from SQL Server database to Oracle through same Tool.
