From LibreOffice Help
In LibreOffice Calc, there is a way to "rotate" a spreadsheet so that rows become columns and columns become rows.
- Select the cell range that you want to transpose.
- Choose Edit - Cut.
- Click the cell that is to be the top left cell in the result.
- Choose Edit - Paste Special.
- In the dialog, mark Paste all and Transpose.
If you now click OK the columns and rows are transposed.
