Please format the merged cell areas as JSON {'top-left':(X, Y), 'bottom-right':(Z, W)}, with (X, Y) indicating the (row_id, column_id) of the top-left cell and (Z, W) the bottom-right cell in the merged regions. Remember that the X, Y, Z, W all start from 1.

The merged cell areas are as follows:
{'top-left':(1, 1), 'bottom-right':(2, 1)}
{'top-left':(2, 2), 'bottom-right':(2, 4)}
{'top-left':(3, 2), 'bottom-right':(3, 5)}
{'top-left':(8, 2), 'bottom-right':(8, 5)}
{'top-left':(13, 2), 'bottom-right':(13, 5)}
{'top-left':(18, 2), 'bottom-right':(18, 5)}
{'top-left':(23, 2), 'bottom-right':(23, 5)}
{'top-left':(28, 2), 'bottom-right':(28, 5)}
{'top-left':(33, 2), 'bottom-right':(33, 5)}.
