1. Open attachment 182009 [details] 2. Save as XLSX Right-click column A, Column width. Compare: should be 2,21 cm, but is 2,20 cm. Spin off from bug 150598. Seen already in oldest of linux-43all repo.
Please note how the cumulative width difference is significant after a few columns. That is not the case when saving the original as xls. So, saving as xls <> saving as xlsX.
