CSV Upload system

I am building a site for a client and require a system to insert records into a database from a csv file. The user will upload the file to the server but I require a function on the site to take the data from the file and insert it into an Access database. I will require this system to be useable on a number of future web sites so flexability is required although it doesn't have to be overly complicated as I can modify the code myself if necessary. I use dreamweaver and ASP VBScript.
