You can use the Store command in the QlikView script to save the output in a CSV file in a specified directory.
You can then automate the Data Loader from the command line. The below link describes how.
We are just starting into a project in which we will be pushing data from QV to Salesforce.com.
Would it be possible for you to send me some information on how you are using Salesforce Data Loader to push QlikView data to Salesforce.
Any help you can provide would be greatly appreciated.
