Just to be clear - you haven't attached an xls sheet. You have attached an xlsx workbook containing three sheets named Sheet1, Sheet2 and Sheet3.
The Excel workbook opens at Sheet2 but Sheet1 also have similar data but structured differently. Which one of the sheets do you want to be used as basis for the Qlik application?
TO load data you can find details at Qlik help - https://help.qlik.com/en-US/sense/June2018/Subsystems/Hub/Content/DataSource/load-data-from-Excel.htm
Attached excel looks like an report in itself. You will have to identify what you information you require to reach to output and perform the cleanup / tranformations.
