It would probably help to state the unexplained difference as a percentage of official C19 death count (and narrow the columns). I took the liberty:

             |   %   | excess  | official| unexplained
    Location | extra | death#  | C19 d#  | difference%
    --------------------------------------------------
    Spain    |  66%  | 19,700  | 12,401  |   59
    England  |  33%  | 16,700  | 10,335  |   61
    NYC      | 298%  | 17,200  | 13,240  |   30
    France   |  21%  | 10,500  |  8,059  |   31
    Holland  |  33%  |  4,000  |  2,116  |   90
    Istambul |  29%  |  2,100  |  1,006  |   109
    Jakarta  |  36%  |  1,000  |     84  |   1071
    Belgium  |  25%  |  2,300  |  1,632  |   43
    Switzer. |  21%  |  1,000  |    712  |   42
    Sweden   |  12%  |  1,100  |  1,160  |   -4
