Is it possible to reload/refresh an open file(.xlsx) using python script in RPi without closing and saving the file itself?

Basically, I want to update a file without closing and opening file using a python script.

without … and saving

? - if reloading without a prior saving you reload the previous, unchanged version. Is that your real goal? From my point of view:

  1. Step: Save using .uno:Save
  2. Step: Reload using .uno:Reload

could be the path to a solution.

proably the real question is about: how to update... ??
