Apache OpenOffice (AOO) Bugzilla – Issue 20138
Lose of time format when saving to xls
Last modified: 2013-08-07 15:15:02 UTC
When you format an empty cell to display hours and minutes (HH:MM) and you save to Excel format, the format is lost re-opening either with MS Excel or with OOo Spreadsheet
This is a known limitation of the Excel export filter. It saves only the range of rows, that are filled with any values (numbers, text, formulas, ...). So if your last value is in row 5, all rows starting from row 6 are not exported (stay completely empty and lose formatting). If you have no contents at all, nothing is exported (especially no formatting). Workaround: Have at least one cell filled in the row with the empty cell or beyond. I will set this issue to "OOo Later", because the fix is not trivial.
