Have you looked at this video?
There is a quick example that shows you how to check your KML file
You can drag over your KML to see how it may appear, this is a great way to test it.
Copy .qvf file to C:\Users\<user>\Documents\Qlik\Sense\Apps
Load Spain Map App
If you view the Data Load Editor - you will see the load statements for the KML file and the data file.
Update the folder path to the location where you saved the .xls file if you want to reload. (you don't have to reload as the data is already part of the app, but I gave it as a reference.)
Note that the ProvinceName - is aliased as "Name" - which matches the Name filed in the data file.

I created an example app and put together two KML files (CCAA and Provincias) with an Excel file, ready to go and reuse in any of your apps.
