One more thing - in addition to reproducing the error, the code has to also
compile and run.

The code you sent is a long way from running.  There are mismatched brackets
(which I can't fix easily because the indenting is all wrong).  Once I got it
executing, I got a ClassCastException from this expression: (Map<String,
Object>) formato.get("data");

There are all sorts of apparent errors where the code keeps updating a map with
the same key and value (map only gets one entry) or the same map instance is
added to a list many times.

After attempting to fix all of this I ran the code with (hojas=1000,
renglones=256) and  the spreadsheet still opened in Excel OK.  Perhaps my fixes
obliterated some important part of the code.


I'm sorry if this is tedious, but it really helps to have some example code
that allows other people to easily reproduce your error.  Can you please
re-attach the example class after making sure that it actually compiles, runs,
and reproduces the error.
