reading xls from asp
 

I need to be able to read any XLS file user wants to
import and provide ability to choose the feilds he wants
to add to the database
ex:
i have a form to submit first, last and email to a
database.
Now i have a xls file with 10,000 records with firstname,
lastname, email, title, company etc.
I should give front end to
choose xls file, provide dropdown with xls feilds and
database table fileds.
does anyone has a sample code to start with.....
thanks in advance
