How do I level a sit-stand desk on an uneven floor?

Most commercial sit-stand desks have adjustable leveling glides on the frame feet — typically plastic or metal feet that screw in or out to raise or lower individual corners. Use a spirit level across the desktop surface to identify which corner needs adjustment, then turn the appropriate foot clockwise to raise it. After adjusting, re-check level across both diagonal directions. On very uneven floors (more than 1/2" difference across the footprint), shim plates under the feet provide more adjustment range.
