Sometimes you may need to transpose the contents of a spreadsheet. Doing this in LibreOffice Calc is easy.
First copy the contents you want to transpose.
Paste the copied contents back in a different location. Right-click and choose Paste Special. From its dialog, choose Transpose. The pasted contents will be the transpose of the original.
