I wonder why it is taking so long for Oracle to address this… If it is technically not feasible, then they should just post a support note saying that 'Oracle can't do this' instead of making all the customers wait for more than half a decade.

The client has been openly mocking the fact that Oracle has been hanging on to a 27-year old Excel technology. We really hope Oracle does something about this. There are already a number of enhancement requests about this for years now, and they just decide to leave it as is.
