Subject Re: [Discussion] [OOXML] Shall we keep all cellStyles from xlsx or not
Date Fri, 31 Aug 2012 01:38:12 GMT
I think we should not have such limitation of 4050 like MS binary file
format, it sounds like a workaround for performance improvement, and MS
2007/2010 have more improvement, we should improve the AOO's capacity to
interop with MS Office 2007/2010 further.  And also for the first, could we
find the key problems from technical view for low performance. Then find
solutions for performance improvement.
