What is a way to convert a batch of .xlsx files to .xls format? I would prefer it to be a command-line solution, but anything is better than opening each manually, and manually saving in the new format.

~~Edit~~

So is there a way to get around that error?

errored: Leaking python objects bridged to UNO for reason pyuno runtime is not initialized, 
(the pyuno.bootstrap needs to be called before using any uno classes) 
python: tpp.c:63: __pthread_tpp_change_priority: 
Assertion `new_prio == -1 || (new_prio >= __sched_fifo_min_prio && new_prio <= __sched_fifo_max_prio)' failed.
