  Hi Shafiq, I could not reproduce the problem, for me it works all the time. Which operating system are you using? Can you remember a situation where this fails regularly and reproducible?
  However, why not simply use the Write Excel operator? Please see the attached process for an example.
  
  Best, Marius
