[#1]

Dear Experties,

As per my requirements I am loading couple of Excel files into Qlikview while loading am getting BIFF error, Manually I have changed the format to .xls but still the same  error happening.

Don’t know does any one facing this issue before

Bcs even u see in excel try copy multiple columns n rows n paste in other shell by double clicking then excel will act as if u r pasting some image n behave in weird manner..

So point is neither u can point to excel nor Qlik..
