I Am Trying To Export Excel From Qlik Sense, And All The Numbers Are Being Represented In Scientific Notation. I Tried To Use NUM() Function And Yet I Don’t See Any Difference

The present version of Qlik Sense does not allow you to do this. We can expect this can be rectified when they release a new update where the master measures have the default format of numbers. But as if now it can be done per object per measure.
