Importing Excel into Oracle

Question

Scenario:
7 users have access to an Excel Sheet.
Any user can use the coldfusion front-end and upload this
excel file into an Oracle database.
Excel sheet has 30 columns, but when they click on
Upload...only 5 0r 6 columns will be filled.
The rest will be null values in the database.
I'm not in a position to make use of Oracle External Tables
neither can I run DB scripts to check for newer Excel Uploads.
As of now I need suggestions on the possible approaches.
Also when user clicks upload:
If col-1 has value then col-2, col-3 should have values and
col-4, col-5 should not have any values.
There will be checks like these in place too.
Please suggest how do I check an .xls file if all these
conditions are filled per row (assuming that there would be 40 rows
per upload per user per day). Do I check the .xls file or do I
check for these validations somewhere else, if yese where and how
??

Either on these forums of the House of Fusion forums, I
recently read a
thread about using excel as a datasource. That may offer you
some options.
The file could be uploaded to a given location. That location
is
configured as a datasource. Use standard SQL operations
against it.
