Qlikview 11 appears to use tab-delimited files for logging. At least that's what Qlikview's very interestingly written FAQ says. I'm sure that information is trivial for you to confirm.
I'm making some assumptions here. The systems where the logs are aren't the same systems where Splunk is, but I'm assuming you have an instance of Splunk Enterprise set up (or possibly Splunk Light, or can use Splunk Cloud - something). I'm also starting from the beginning - skip the sections that you've already got sorted out. And lastly, so that this doesn't turn into a 7 page instructible, I'm only including a summary as sort of a guideline. Some research and work on your part is required, though it you get stuck feel free to create a new, targeted Question for the individual problems!
Since the log tiles are tab delimited, open a few of them up and take a look at them. If they look useful, you'll want to download and install the Universal Forwarder and point it to your indexer. Set up data inputs, fiddling with the sourcetypes and stuff to get them so they have the right timestamp and the fields are identified. There's a lot of good help on doing this in the Getting Data In manual sections. You might have to do some research to find out WHAT the fields in the logs are. That's a Qlikview question more than a Splunk question.
By "Transformation" I don't know what you want or need. I think if you have data coming in and defined in fields and all that, you will probably be able to just start searching and transforming and using the built in tools to start making charts and visualizations of the data that you can add to a dashboard. This is a big topic but mostly not real hard, but if you aren't very familiar with it some of the Splunk docs (specifically, the Splunk Search Tutorial and the free online Splunk Tutorial) may be very helpful.
Then it's all fun and festivities after that!
