Cannot Load or Transform Data from Excel

[Yafei]

I am trying to load data from excel, but both Load and Transform Data buttons are not available.  I had to save my excel to csv files first and load multiple times to load different tabs. Please advis, thanks!

You will need to check the corresponding check box to make these buttons enabled. You have just highlighted the entry but not selected the box in left pane.
