Created attachment 64330 [details] Initial spreadsheet file While working on an OpenDocument spreadsheet I had big surprises with Excel file exports after unpdating my LO to 3.5.5. The enclosed document is quite small as .odt, but becomes very large (>1Mb) as .xls file. I tried to do the same export under LO 3.4 Windows, no problem encountered.
