Need A Good File Import Script

[dlebowski]

I currently have an uploader that runs on my site that allows the user to upload a .csv file to the server, it then prompts them to match up each field in the file with the corresponding field in the database table.  It works pretty good, but a little bit clunky and with the way I currently have it setup, it will only insert into the database, I can't update.  Does anyone know of a good .csv uploader that will let the customer match up the columns in the .csv file with the fields in the database as well as do updates and inserts with records in the database?  Any direction would be appreciated.  Thanks!
