From foe to friend

Excel was previously a book with 7 seals for me. I knew that one can thus do a lot. Also I get official always one or the other Excel annex where I thought, not bad, I should but ranwagen sometimes.
So in a quiet hour to have a go at the enemy, and with the guidance of H. Video Zinkann a seal was removed after another. I will not pretend Excel has become the enemy to friend, but even that can happen.
Thanks for the informative support Mr Zinkann.
