Excel Workbooks start with worksheets to right

Is this what you mean?

• Open Excel
• On the default workbook
• click "File" in Ribbon
• Select "Options"
• Select "Advanced"
• Scroll down to "Display" section
• Under "Default Direction" select "Right-to-Left" option
• Click "OK"
• Click File on Ribbon again
• Click "New"
• The new workbook that opens will have columns reading from right to left.

You will need to do the steps again and select Option "Left-to-Right" after saving and closing the new workbook.

When you re-open the new workbook it should show columns right to left automatically.

You're welcome.

I remember it taking me ages to find the way to do it first time I needed to.

When you have columns reading from right-to-left then scripts that are written right to left (e.g. Hebrew and Arabic) text will automatically get entered right to left in a cell.
