Re: enhancement request: 'shortest roundtripping' representation of values for file export - with patch proposal

xls stores only binary numbers.  You will not be able to store long doubles.

xlsx leaves pointer->output.decimal_digits as -1 and gets shortest
representation.  Comment out 1483 in xml-sax-write.c and you ought to
get the same.  Note: this will break a lot of tests that will suddenly
see unexpected changes!
