Actually, although the problem actually doesn't manifest now for majority of cases, it still is reproducible like this:
1. Create a new spreadsheet 2. Go to last column: AMJ (Ctrl+Arrow Right) 3. Change the width of column AMJ 4. Save as XLSX. The reason is the code in sc/source/filter/excel/xetable.cxx introduced in https://git.libreoffice.org/core/+/64274b38f6cc50a8bb49f114f1ac9e7c1c3b3c4f back in 2009: that was the commit introduced export to XLSX (integrated to LO from Go-oo). The code starts with this comment: > // if last column is equal to last possible column, Excel adds one more which is directly taken from the older code that exports to XLS binary formats. Obviously, this is just a left-over from copy-paste. When writing to OOXML format, Excel doesn't do that.
